Kyle Shanahan Limited at Camp + Mahomes Knee Brace Update

The biggest story hovering over the opening week of training camps is the health of San Francisco 49ers head coach Kyle Shanahan, who suffered a severe concussion and other injuries in a July 14 car accident. Shanahan is beginning camp in a limited capacity, with assistant head coach and offensive line coach Chris Foerster assuming some of his head coaching duties in the interim. The team expects Shanahan to be cleared before the season opener, but until then the 49ers are navigating a genuine leadership challenge at the top of their coaching staff. Rams HC Sean McVay, whose team is a division rival, weighed in Sunday, saying he spoke with Shanahan directly and that the coach "has an incredible perspective" on his recovery — a telling sign of how widely this situation is being felt across the league.

The other major health storyline involves Patrick Mahomes, who has been cleared by Andy Reid for full practices but will wear a knee brace throughout camp as he continues his rehab. Mahomes himself said he can still move and be himself with the brace and views this stage as a checkpoint in his recovery process. He has also been consulting with Tom Brady during rehab. Meanwhile, the PUP list is filling up fast across the league — Ravens DT Nnamdi Madubuike (neck, out since Week 2 last season), Seahawks S Nick Emmanwori (arthroscopic ankle surgery), Bears CB Kyler Gordon, Chiefs DL Omarr Norman-Lott, Bengals DL B.J. Hill, and 49ers TE George Kittle have all landed there to open camp.

The connecting thread here is clear: training camp 2026 is opening under a cloud of injury uncertainty at the very highest levels of the game. From a franchise QB managing a knee brace, to a Super Bowl-caliber head coach limited by a serious accident, to a wave of PUP designations across the roster landscape, fantasy managers need to be paying close attention to practice participation reports from Day 1. The Shanahan situation in particular adds genuine schematic uncertainty to a 49ers offense that was already a popular target in drafts.

Tomorrow, watch for Shanahan's first official practice-day update from Santa Clara and any clarity on Kittle's PUP timeline, both of which carry major fantasy implications for the 49ers' skill players. Also keep an eye on Mahomes in full-squad drills — how freely he moves in the brace will be a key data point for Chiefs skill position values heading into draft season.
