Jarrett Patterson plays at least one offensive snap for San Francisco in its Week 1 game against the Los Angeles Rams on September 10, 2026. The take is WRONG if he plays zero offensive snaps, including the cases where he is inactive, is not on the roster, or appears only on special teams. Special-teams snaps do not count.
Jarrett Patterson is NOT San Francisco's starting left guard in its Week 1 game against the Los Angeles Rams on September 10, 2026. The take is CORRECT if the official game book's lineup card names anybody other than Patterson at left guard, and WRONG if it names Patterson there.
On 2026-09-10, the depth chart published at 49ers.com/team/depth-chart still carries a "Last Updated" stamp dated EARLIER than 09/02/26. Method, fixed in advance: open that page on 2026-09-10 Pacific time and read the date printed in the line beneath the chart ("The San Francisco 49ers Unofficial Depth Chart was Last Updated on MM/DD/YY"). A stamp of 09/02/26 or later grades this WRONG. A page that does not load or prints no stamp grades this WRONG.
San Francisco's public depth chart carried an empty box at left guard from August 27 until this week. Read at 2:52 p.m. Pacific on Sunday, it is stamped 09/4/26 and lists Connor Colby first at left guard and Carver Willis second. It also lists Kaelon Black second at running back ahead of Jordan James, which is the other job Kyle Shanahan called fluid on August 31, and George Kittle and Nick Bosa as starters. Colby was the incumbent in July, was passed by Robert Jones and then by Willis in August, and is first again on the club's own page. Jarrett Patterson, traded for to compete at guard, is listed second at center. The chart predates three roster moves and has one empty box left, at long snapper. The first Melbourne practice is Sunday at 7:50 p.m. Pacific.

The 49ers' published depth chart lists a first-team name at twenty-eight of its twenty-nine positions. Left guard is the twenty-ninth, and the only man in the row, Carver Willis, sits in the second column. Kyle Shanahan said Monday he does not know who starts there against the Rams on September 10, and gave the reason: the Thursday opener took away the three practices he normally decides on, and the club added Jarrett Patterson to the group. Connor Colby has six career starts, Patterson twenty-one, Willis none. San Francisco signed a fifth offensive lineman, Foster Sarell, to the practice squad on Tuesday afternoon.

San Francisco's cut to the initial roster, first through named reporters and then through the club's own release at 3:50 p.m. Pacific. Robert Jones released at 1:35 p.m. and Jarrett Patterson acquired from Houston seven minutes later. Mykel Williams to reserve/PUP and out at least four games. Christian Kirk to injured reserve with a designation to return. Brett Toth and Nick Zakelj to season-ending injured reserve. Deion Jones released five days after the 49ers traded Zamir White for him. Jalen Stroman waived three days after playing every defensive snap in Las Vegas. Thirty-nine moves, fifty-two men, and no punter or long snapper on the list.
