George Kittle is out because he suffered a right hamstring injury in the 49ers’ Week 1 game of the 2025 NFL season against the Seattle Seahawks and was placed on injured reserve.

What happened

  • Kittle injured his right hamstring while running a deep route in the first half of the Sept. 7, 2025 season opener vs. Seattle and was ruled out for the rest of that game.
  • The injury was serious enough that he was placed on short-term injured reserve, which automatically sidelined him for at least four games.

How long was he expected to be out?

  • Early reports from the team and league insiders put his recovery timeline at about three to five weeks, lining up with a possible return once the four-game IR minimum was satisfied.
  • Team leadership later indicated Week 6–7 games (Buccaneers/Falcons window) as the first realistic return targets once Kittle became eligible to play again.

Latest status and context

  • As of mid-October 2025, Kittle said his hamstring was actually a “full tear,” though located in a way that allowed for a faster-than-normal return compared with more severe hamstring tears that can take three to six months.
  • Around that time he publicly stated he planned to return for a home game against the Falcons, signaling that the team viewed his recovery as on track and not a season-ending issue.
