Brett Toth is NOT on San Francisco's initial 53-man roster after the August 30, 2026 cutdown. The take is CORRECT if his name is absent from the club's published initial 53, including the cases where he is waived, released, waived/injured, placed on injured reserve, or reaches an injury settlement. It is WRONG if the club's published initial 53 contains his name, whatever his health designation.
Nick Martin is on the San Francisco 49ers' initial 53-man roster announced at the August 30, 2026 cutdown. The take is WRONG if he is waived, released, traded, or placed on injured reserve or reserve/PUP before that roster is submitted, and WRONG if his name is absent from it for any other reason.
Nick Bosa and Christian McCaffrey did not take part in drills during the portion of San Francisco's first Melbourne practice open to reporters, per Matt Maiocco at NBC Sports Bay Area and Matt Barrows at The Athletic. San Francisco plays the Rams at the Melbourne Cricket Ground on Thursday at 5:35 p.m. Pacific. Reporters leave before team drills, and the club was not required to file a participation report, so what either man did after that is not public. Shanahan said the time difference meant he did not have to talk about injuries until the following day, and did not. George Kittle and Mike Evans practised. Barrows listed six men back from injury: Renardo Green, Romello Height, Jacob Cowing, Vederian Lowe, Gracen Halton and Luke Gifford. Five of the six who sat out the September 2 practice in Santa Clara are on that list; James Thompson Jr. is on no list either way. The club named eight captains, all eight returning from 2025, and Bosa and McCaffrey are two of them. Brayden Willis is back on the practice squad, which now sits at seventeen.

Kyle Shanahan confirmed on Tuesday that Kurtis Rourke broke three ribs in the preseason opener, twelve days after the club said the X-rays taken in the stadium showed nothing broken and sent him to hospital for more imaging. Rourke does not play in Thursday's finale at Las Vegas and Adrian Martinez takes the last game of the third quarterback competition. Shanahan also named Christian Kirk and Vederian Lowe as candidates to open the regular season on injured reserve, a designation that costs each of them at least the first four games and costs San Francisco a roster spot on Sunday; said Dominick Puni is most likely back in the concussion protocol; put Nick Bosa, Jacob Cowing, Upton Stout and Mike Evans back at practice next week rather than this one; and left the left guard job to Connor Colby and Carver Willis with Robert Jones hurt. The club signed defensive lineman Jah Joyner on Thursday morning and placed Victor Dimukeje on injured reserve to make room.

San Francisco has taken three players off injured reserve since Monday and published none of it. The league's waivers wire carries Titus Leo and Tanner McLachlan dated August 25, both reading Terminated Via Waivers, all contracts, and Xavier Thomas dated August 26 with the same wording. The step before it differs by man: Leo and Thomas were waived with an injury settlement, McLachlan with no recall. The club's transaction log's newest entry is Tuesday's Deion Jones trade. Over The Cap and Spotrac each now list five men on San Francisco's injured reserve totalling $5,604,563 and neither carries any of the three, while the club's own roster page still lists seven under Reserve/Injured, those five plus Leo and Thomas. Also: Kyle Shanahan named Christian Kirk, Vederian Lowe and Nick Martin as candidates to open the season on injured reserve, a designation that only works for a player who makes the initial 53 first; Nick Bosa's knee has a name in print for the first time; Renardo Green's imaging result is still unpublished six days after the coach ordered it; and the club hosted a free-agent defensive end on a visit Wednesday.

San Francisco practised for the last time in training camp on Tuesday morning and Kyle Shanahan said afterwards that the left guard competition is close to being decided between Connor Colby and Carver Willis, with Robert Jones removed from it by a calf injury Shanahan put at around the Australia trip. Matt Maiocco had Willis taking the first-team snaps. Dominick Puni practised and then reported residual symptoms and is most likely back in the concussion protocol. Shanahan named Christian Kirk and Vederian Lowe as possible candidates to start the season on injured reserve, hedging both. Mike Evans, Jacob Cowing, Upton Stout, Romello Height, Kyle Juszczyk, Kirk, Kurtis Rourke and Nick Bosa did not practise across two published absence lists that do not match. Height's injury is an ankle and Juszczyk's finger is fractured. The 49ers play at Las Vegas on Thursday at 5:00 p.m. PDT and the roster is due at 53 at 3:00 p.m. PT on Sunday.

The first weekly column off the 53-man tracker. Six days of camp produced six grade changes, four players in and four out, and not one of them changed which 53 men this site projects onto the initial roster. What the confidence grade measures, why Vederian Lowe lost a point without his job being in question, and the count that explains the churn: 87 active players plus four on the physically-unable-to-perform list is 91 bodies, which under either reading of the league limit leaves zero open spots.

The 49ers opened camp Sunday, signed a defensive lineman they have employed since 2019, and got three snaps out of the man they are counting on to stand behind a 38-year-old left tackle.
