San Francisco 49ers starting defensive tackle Alfred Collins suffered a torn patellar tendon during the team's Tuesday practice in Australia, an injury that will keep him out for the 2026 season. Coach Kyle Shanahan announced the injury Wednesday and confirmed Collins will not return this year.
According to Shanahan, the injury happened in Tuesday's practice just before the team started 11-on-11 drills. Collins will require surgery and go on injured reserve in the near future. The loss comes on the heels of defensive end Sam Okuayinonu landing on injured reserve with a broken foot that will also require surgery over the weekend.
"Alfred tore his patellar tendon yesterday," Shanahan said. "That was a big loss. We've lost two D-lineman pretty much for the year after cuts and before the first game which has been a huge challenge. I'm hurting for Alfred... It was real unfortunate for him."
Collins was a second-round pick in the 2025 NFL draft and played in 16 games last season, posting 17 tackles, a sack, two forced fumbles and two fumble recoveries. He was one of the heroes of San Francisco's Week 5 win against the Los Angeles Rams, forcing and recovering a fumble at the Niners' 1-yard line to help preserve a fourth-quarter lead.
With Collins out of the mix, the Niners will enter Thursday night's season opener against the Rams with C.J. West and rookie Gracen Halton as the only healthy options on the 53-man roster who can start next to fellow defensive tackle Osa Odighizuwa. Undrafted rookie James Thompson Jr. is another possibility, but he has missed practice with a hamstring issue.
