Bo Nix is out for the season because he fractured a bone in his right ankle and will undergo season‑ending surgery, which rules him out for the rest of the Broncos’ playoff run.

What happened

  • Bo Nix suffered the ankle injury late in the Broncos’ 33–30 overtime win against the Buffalo Bills in the divisional round of the 2025 NFL playoffs.
  • The injury occurred on one of the final plays in overtime, when his right ankle twisted awkwardly, leading to a confirmed fracture.

Why he’s out for the season

  • Head coach Sean Payton announced after the game that Nix had broken a bone in his right ankle and would need surgery, ending his season immediately.
  • The surgery, scheduled for the following Tuesday in Birmingham, Alabama, means he will miss the remainder of the playoffs, with Jarrett Stidham taking over as the Broncos’ starting quarterback.

Quick Scoop context

  • Nix finished the game despite the injury, throwing for multiple touchdowns and helping secure Denver’s first playoff win since Super Bowl 50, which made the news of his season-ending status especially shocking to fans and forums.
  • Fan discussions online highlight both how sudden the announcement felt—since he looked “fine” in the postgame—and how dramatically it changes expectations for the AFC Championship and a possible Super Bowl run.

TL;DR: Bo Nix is out for the season because he broke a bone in his right ankle on one of the last plays of the overtime win vs. the Bills and now needs season-ending surgery.
