The 49ers won by 22 and came out of it needing a receiver and a lineman

Kyle Shanahan took a conference call on Monday, a day after San Francisco beat Miami 35-13, and gave four verdicts. Two of them cost the 49ers a player apiece for at least three weeks.

Demarcus Robinson has a high-ankle sprain. "Any time it's a high ankle, we don't have a timeline, but high ankles in general are anywhere from three weeks at the best, which is very rare, to six weeks," Shanahan said. "So, we'll see how it goes, but most likely he'll be an IR candidate here." James Thompson Jr., the rookie defensive tackle who walked to the locker room in the third quarter, has the same injury and the same range.

Romello Height broke his hand and has surgery on Tuesday. Shanahan did not rule him out for Arizona: "An outside chance to be ready for the game Sunday, but he needs to get surgery on that tomorrow." Mike Evans, who took himself out of Sunday's game with a hip, will be managed through the practice week.

The receiver room is now five men, and two of them were barely playing two weeks ago#

Robinson was San Francisco's second-most-used receiver by snaps in Melbourne, on the field for 41 of 65 offensive plays, and he caught the team's first touchdown of the season on a 39-yard throw. Against Miami he had three catches for 34 yards on three targets before he was carted off in the second quarter. He has played 57 offensive snaps this season. Three to six weeks from Sunday puts his return somewhere between the middle of October and the start of November.

Put him on injured reserve and the club's roster carries five wide receivers: Deebo Samuel, Evans, Jacob Cowing, KhaDarel Hodge and Jordan Watkins. Injured reserve already holds three wide receivers in Ricky Pearsall, De'Zhaun Stribling and Christian Kirk, and it would then hold four. Kirk is the one with a date on it, and the date is not this week. "He's not an option this week," Shanahan said. "He's not there yet, so we've got to wait another week on him at least."

The reshuffle has already happened once. Cowing and Hodge were on the field for six offensive snaps between them in Melbourne. Against Miami they took 44, Cowing 24 and Hodge 20, because Stribling was on injured reserve and Robinson left at the half. Cowing has played 29 offensive snaps this season and has not been thrown to once.

Watkins is the other name, and he has been inactive for both games. The practice squad holds two receivers, Wesley Grimes and Will Pauling, and neither has been on the field for a snap this season.

None of which stopped the offense on Sunday. Brock Purdy went 20 of 22 for 287 yards with the room that thin, and ten of those twenty completions went to George Kittle, Christian McCaffrey and Kyle Juszczyk. Exactly half of what he completed went to men who are not wide receivers.

The defensive line has lost three men in two games, and the club has already made calls#

Height was on the field for 32 of 59 defensive snaps against Miami and Thompson for 21. That is 53 between them, thirteen more than Nick Bosa's 40. Sam Okuayinonu and Alfred Collins are on injured reserve, and Mykel Williams is on the physically unable to perform list.

Matt Barrows of The Athletic asked Shanahan on Sunday whether Leonard Floyd, who played here in 2024, was an option. "I mean, we always look at that," Shanahan said. "That's stuff that, as soon as we lost Sam and stuff, we talked to Leonard, we talked to a couple of people. But we'll see how this goes. There's no one that's for sure. But we'll see. With losing James possibly today, we'll see what his ankle injury is. It's a little different position with inside players, but we've lost about three guys here in the last two games, so we've got to do something eventually."

The club has already done the cheap version of this once. On September 19 it put Stribling on injured reserve and signed Ogbo Okoronkwo to the 53-man roster the same afternoon, one move with two halves, and the league transaction wire files Okoronkwo's half as a free-agent signing rather than an elevation. He was not a new arrival. He had been on the practice squad since the cutdown and had already played in Melbourne on a standard elevation, 18 of 61 defensive snaps. Against Miami, in his first game as a man actually signed to the 53, he played 16 of 59. The club converted a player it already had, and his share of the defense went down.

That is the shape of the answer available to San Francisco this week and the reason a signing from outside is not automatic. The 49ers carry four defensive linemen on the practice squad in Vincent Anthony Jr., Kevin Givens, McKinnley Jackson and Sebastian Valdez. Nine men are listed at defensive line on the active roster, and three of the nine are Height, with a hand that needs surgery, Thompson, with the high ankle, and Okoronkwo, who was not signed to the 53 until Saturday.

Williams is the one piece of good news, and it is a week away. He became eligible to practice this week and the club is holding him anyway. "If we let him go, he was just going to do individual this week, so just don't feel the risk/reward of letting him go this week when he's just doing individual," Shanahan said. "We're going to try to hold him so we can hopefully replicate that on the side and get him going for practice, hopefully next week." Both he and Kirk can be activated after Week 4.

What the week has to produce#

Three routes are open at receiver, and the club has not said it will take any of them. It can sign a free agent to the 53, which is the route that needs Robinson's roster spot and therefore needs the injured-reserve paperwork first. It can sign one to the practice squad and elevate him on Saturday, which is cheaper and slower. Or it can do neither and dress Watkins, who has been on the roster since the 53 was set and inactive for both games. On September 16, with Stribling already gone, Shanahan said San Francisco had as much depth at the position as any team in the league and did not need to add anybody. He has not been asked the question again since Robinson went off on the cart.

The first Week 3 practice report is due Wednesday, which is when the hip and the hand stop being adjectives and become participation designations.
