Every call on this site goes on a public ledger and gets graded. The misses stay up.

The trade reported Tuesday afternoon is now on the record. The 49ers announced at 1:39 p.m. Wednesday that they have acquired DeForest Buckner from Indianapolis for their 2027 fourth-round pick. The same release named the move that pays for it: cornerback Jack Jones is released.

The terms, as the club wrote them. One pick, a fourth-rounder in 2027, and nothing else in either direction. The release carries no mention of a physical, which was the open item on Tuesday night.

Buckner's line, per the club. He is 32. Across 11 seasons with San Francisco and Indianapolis he has played 158 games with 153 starts, 75.5 sacks and nine forced fumbles. This season he started seven games for the Colts: 31 tackles, 4.0 sacks, three passes defensed and one fumble recovery.

Who Jones was on this roster. He signed in June for $1,215,000 with nothing guaranteed, per Over The Cap. He was active for all seven games, per Kyle Dvorchak at NBC Sports, and the club credits him with 11 tackles and three passes defensed. At Atlanta he played 23 of the 49ers' 68 defensive snaps and three on special teams, per the official game book. One of those 23 was the third-and-8 incompletion on which he was flagged for pass interference, 20 yards, on the drive that ended in Drake London's touchdown.

Why he was playing at all. With Upton Stout out, Deommodore Lenoir moved inside to the slot and Jones took Lenoir's outside spot in passing situations, per Kyle Posey at Niners Nation. Posey writes that the 49ers turned to rookie Ephesians Prysock once Jones came off the field. The book has Prysock at two defensive snaps.

The cornerback room now. Five on the 53: Lenoir, Renardo Green, Stout, Siran Neal and Prysock. Stout, out with a shoulder, is expected back to full practice after the bye, Kyle Shanahan said Monday. Brandon Codrington is the practice squad's only cornerback. Nate Hobbs remains on injured reserve.

The defensive line now. Ten on the 53 with Buckner, up from nine. Nick Bosa is one of the eight Shanahan named Monday with a chance to return against Las Vegas.

The 53 is still full. The swap was one for one, so the math from Tuesday holds. Demarcus Robinson and C.J. West, both on injured reserve and both on Shanahan's list, each need a spot to come back. That is two more players off the active roster if both return Nov. 8.

Wagoner expects more. Nick Wagoner of ESPN, on Sactown Sports' Matt & Kayla Show Wednesday, said he would be surprised if the 49ers made no further move before the deadline, and named edge rusher as the likeliest target. The deadline is Tuesday, Nov. 10, two days after Las Vegas.

And the kicker. Wagoner also said on the same show that the 49ers could bring in other kickers for a look, even with Eddy Pineiro keeping the job for now. "I think the extra-point thing is a thing," he said. John Lynch said on KNBR on Tuesday that there would be no tryout. Pineiro has made 21 of 25 extra points.

Sources. The trade terms, Jones' release, Buckner's career and 2026 lines and Jones' 2026 tackles and passes defensed: 49ers release, Oct. 28, 2026. Snap counts and the pass interference: NFL official game book, 49ers at Falcons, Oct. 25. Jones active in all seven games: Kyle Dvorchak, NBC Sports, Oct. 28. Jones' and Prysock's roles: Kyle Posey, Niners Nation, Oct. 28. Stout's timeline and the return list: Kyle Shanahan via the 49ers, Oct. 26. Wagoner: Sactown Sports, Oct. 28. Lynch: KNBR, Oct. 27. Pineiro's extra points: ESPN. Jones' contract: Over The Cap. Roster counts: the 49ers' roster and the Oct. 28 release.

Nick Bosa Practised For The First Time Since August 3

Nick Bosa practised Wednesday for the first time since August 3, in individual drills and in team periods, per Nick Wagoner at ESPN. It is his first full practice since he tore the right anterior cruciate ligament in Week 3 of last season. He said afterwards that once a session reaches team work there is no governor on it, and that he is confident about Week 1. Ian Rapoport reported Wednesday morning that Bosa and George Kittle both travel to Australia. Kittle has now had three straight days of team work, dated to Monday by John Lynch. Six players sat out, three fewer than Tuesday: Renardo Green, Jacob Cowing, Luke Gifford, Gracen Halton, Romello Height and James Thompson Jr. Jack Jones was on neither list and did no work with the team. Left guard is still not named. The club hosted defensive tackle McKinnley Jackson on a visit and signed nobody.

Carver Willis Graded Last Among The 49ers Linemen A Week After Grading First On The Team

PFF's grades from the 49ers' 41-17 preseason win at the Chargers, read one player at a time. Carver Willis graded last among the eleven San Francisco offensive linemen charted, a week after grading first on the whole team against Tennessee. Nick Zakelj, re-signed six days ago and absent from the head coach's list of left guard competitors, graded second among every lineman in the game. Two undrafted rookie defensive tackles posted the best defensive grades on the roster, Sincere McCormick ran for the most yards on the field and graded as the team's worst pass blocker, and Jack Jones took the best coverage grade while Darrell Luter played the most snaps and took the lowest among the corners who finished.

Jack Jones Broke Up Two Passes At The Chargers. Nate Hobbs Has Not Played A Preseason Snap.

The official game book from Thursday night at SoFi Stadium credits Jack Jones with two passes defensed, the most by any 49er in a game the team finished with seven, and 29 of San Francisco's 59 defensive snaps. Nate Hobbs pulled a groin at the joint practice with Tennessee on August 11 and does not appear on the participation page of either preseason game. Kyle Shanahan said on August 13 that Hobbs would be out a few weeks. The roster is due Sunday, August 30 at 3:00pm PT. This board moves Jones from 5 to 7 and inside the projected 53, and Hobbs from 6 to 5 and outside it.

On the record

Called Shots →
Held upAug 15, 2026

None of the three defensive backs San Francisco worked out on August 14, 2026, Bryce Hall, Troy Pride Jr. and Corey Mayfield Jr., signs with the 49ers on or before August 20, 2026. The take is CORRECT if the club's transaction log carries no signing of any of the three by the end of August 20. It is WRONG if any one of them is signed in that window, whatever the corresponding move is.

The case for it is Saturday. Two of the three secondary injuries that produced the tryouts, Jack Jones with a hand and Marques Sigle with an oblique, were in uniform at the August 15 practice two days after leaving the opener, and Bonilla writes that Jones appears to have avoided a setback. The roster is at 90 chargeable players against a limit of 90, counted table by table on August 15, so signing any of the three costs a man already in the building his job. A club that has a corner back on the field does not usually pay that price. The case against is Nate Hobbs, the one of the three injured defensive backs with a stated timeline on him, a few weeks per Kyle Shanahan, and the Chargers game on August 20 is a game San Francisco has to field a secondary for. A second injury in the group on August 15 or at Tuesday's joint practice in Los Angeles would very likely make this wrong on its own.

The 49ers ran Las Vegas out of its plan before they took the ball away

San Francisco beat Las Vegas 38-17 on Sunday and is 7-1. The five second-half takeaways will be remembered, but the game was settled earlier. The 49ers' first three drives went 37 plays and 242 yards, took 19 minutes and 23 seconds and ended in touchdowns, and San Francisco ran 25 times for 125 yards before halftime. Las Vegas had the ball for 71 seconds in the first 13 minutes. Trailing by 11 at the half, the Raiders ran six times and threw 24 times after it, and Klint Kubiak said that being in position to throw on every down produces interceptions. The pass rush did not cause the turnovers: Cousins was hit twice on eight first-half throws and four times on 24 second-half throws. Two takeaways were punched out of receivers' hands, and one came off a fumbled exchange. The second half also showed a cost. San Francisco threw an interception, was stopped on fourth-and-1 at its own 40, and allowed 222 kickoff-return yards, and Las Vegas started three drives in 49ers territory. The game moved San Francisco's season turnover margin from minus-3 to plus-1. Las Vegas has now allowed 30 or more points six weeks running, so Dallas on Sunday is the first test of whether the formula holds.

The 49ers trade a sixth-round pick for Keenan Allen

San Francisco acquired wide receiver Keenan Allen from Indianapolis on Tuesday, deadline day, for a 2027 sixth-round pick, the league transaction wire shows. It is the second trade between the clubs in three weeks, after DeForest Buckner on Oct. 27. Allen, 34, played at Cal and is a six-time Pro Bowler with 1,095 career catches, eighth all time. He had 40 catches for 351 yards and one touchdown in eight games for the Colts, their team lead. The club placed Gracen Halton on injured reserve with a fractured ankle the same afternoon, and its roster page showed 52 on the active roster before Allen was added. Allen joins a receiver room missing Mike Evans and Deebo Samuel Sr. last Sunday. He caught four passes for 26 yards against Dallas in Week 9, and the 49ers play at Dallas on Sunday.

Five takeaways in one half, and the 49ers never sacked Kirk Cousins

San Francisco beat Las Vegas 38-17 at Levi's Stadium on Sunday and is 7-1. The 49ers scored touchdowns on their first three possessions, did not punt, and ran 43 times for 190 yards. Las Vegas turned the ball over on five of its six second-half possessions: Jaden Dugger's 35-yard interception return on the first play of the half, two forced fumbles, and interceptions by Renardo Green and Malik Mustapha. The official game book credits San Francisco with no sacks and six quarterback hits, two of them on the plays Green and Mustapha intercepted. Nick Bosa played 39 of 50 defensive snaps in his first game since Sept. 20, and DeForest Buckner played 34. Jordan Watkins caught all four of his targets for 86 yards and his first NFL touchdown. Christian McCaffrey's 12-yard catch set the Super Bowl-era record for touchdown catches by a running back and was Brock Purdy's 100th touchdown pass. Gracen Halton broke his ankle and is out for the season, Shanahan said; Green (back) and Deommodore Lenoir (foot) did not return.

Six 49ers are out at Atlanta, and Shanahan may dress fewer than 48

The 49ers ruled out Nick Bosa, Mike Evans, Deebo Samuel, Luke Gifford, Marques Sigle and Garret Wallow for Sunday at Atlanta. Christian Kirk, Siran Neal and Upton Stout are questionable; Kyle Shanahan called Kirk's tag procedural. The club released defensive lineman Ogbo Okoronkwo on Friday, opening a spot on the 53. Shanahan said the team may go into the game with fewer than the maximum 48 active, with quarterback Kurtis Rourke and possibly lineman Enrique Cruz Jr. the last two available, something he could not recall happening in his career.

Week 3 takeaways: Arizona had the ball for 38 minutes and never led

San Francisco is 3-0 after a 36-30 win over Arizona. The 49ers led from the 8:26 mark of the first quarter to the end while running 50 offensive plays to Arizona's 81, and averaged 8.7 yards a play to Arizona's 4.5. Purdy was 15 of 27 for 297 yards, four touchdowns, no interception and no sack. Kittle caught both fourth-quarter touchdowns, the second two snaps after his own holding penalty wiped out a 45-yard Purdy touchdown run. Jordan Watkins caught two passes for 60 yards in his first game of the season. The defense was on the field for 87 snaps with nine linemen dressed. Evans (rib or oblique) and Trent Williams (stinger) left and did not return; Greenlaw left with a quad.

My August Estimate Said $57 Million. Over The Cap Says $45,532,257.

My August Estimate Said $57 Million. Over The Cap Says $45,532,257.

Read in both books Thursday, September 10, 2026: San Francisco leads the NFL in cap space at $45,532,257 on Over The Cap and $50,209,913 on Spotrac. Over The Cap's charges rose $22,523,241 since August 27, against a modelled $9,842,532 to $10,825,332, so the August estimate missed by between $11,697,909 and $12,680,709. The practice squad landed inside the modelled range at $4,617,000 and dead money was light by $756,599. The miss is the reserve lists: injured reserve, reserve/PUP and one suspension carry $39,632,011, of which $3,419,563 reached the published number in August, and none of the three was an input to the estimate. The gap between the two books has collapsed from $11,991,268 to $4,677,656, and $6,302,000 of what is left is the two sites filing one player's absence under different headings at different prices. Trent Williams remains $2,499,997 apart, unchanged for thirty-three days, and that one contract is larger than the entire $2,059,992 active-roster difference. Of three calls resolving September 15, two are on track right and one is wrong by $322,344.
