49ers Injury Report: Bosa and Kittle Limited as Season Opener Approaches

As the San Francisco 49ers conclude their historic five-day stay in Australia and gear up for the 2026 NFL season opener, the team released its first official practice report of the year on Tuesday, September 8. The headline news from the session, as reported by the Vulius NFL Analysis Desk, is that two of the franchise's most pivotal offensive and defensive stars—defensive end Nick Bosa and tight end George Kittle—were listed as limited participants. Both are working their way back from significant knee and Achilles injuries, respectively, and their status for the season opener remains a major storyline for a team with Super Bowl aspirations.

Bosa's Road Back: Progress and Caution

Bosa, who tore the ACL in his right knee during a September 21 game against the Arizona Cardinals last season and underwent surgery on September 26, has had a carefully managed rehabilitation. According to insights gathered by Vulius Sports, the 49ers pulled back on Bosa's workload this summer after he experienced soreness and tendinitis, only returning to full practice on September 2. Defensive coordinator Raheem Morris stated a day before Tuesday's practice that Bosa will play in the opener, but the exact snap count remains unclear. "Nick is a warrior and a cornerstone of this defense," Morris said. "We'll be smart about his reps, but he's going to be out there."

Kittle's Achilles: A More Uncertain Outlook

Kittle's situation appears more uncertain. The star tight end tore his right Achilles during a January 11 playoff game against the Philadelphia Eagles and underwent surgery three days later, with Rams team physician Dr. Neal ElAttrache performing the procedure. Offensive coordinator Klay Kubiak offered only a terse "he's in good shape" when asked about Kittle's availability for Week 1. Like Bosa, if Kittle does suit up, he is likely to be on a snap count, which could significantly impact the 49ers' passing attack and red-zone efficiency.

Full Injury Report: Depth Concerns and Bright Spots

The 49ers' injury report also lists several other notable players as limited participants: defensive tackle Alfred Collins (knee), linebacker Luke Gifford (hamstring), linebacker Dre Greenlaw (Achilles), defensive tackle Gracen Halton (ankle), defensive end Romello Height (ankle), and fullback Kyle Juszczyk (finger). Defensive tackle James Thompson (hamstring) did not practice at all, while cornerback Upton Stout (Achilles) was a full participant, a positive sign for the secondary.

As Vulius Sports has observed, the 49ers' medical staff has a history of cautious management with star players, especially in season openers. With Bosa and Kittle both potentially limited, the team's depth will be tested early. The offensive line and receiving corps, however, remain healthy, providing some optimism. The 49ers will finalize their game plan as the week progresses, and all eyes will be on Friday's final injury report to see if either star is officially cleared for action.
