NFL training camps are in full swing across the country as all 32 teams have reported by the final week of July 2026. With the regular season opener between the New England Patriots and Seattle Seahawks set for September 9, these next six weeks will determine who starts, who sits, and who finds themselves on the outside looking in. Injuries — always the dominant story of training camp — have already begun shaping roster decisions. Here is the latest on the most significant names whose health will define the early season.
Patrick Mahomes: The Chiefs Hope for a Full Return
All eyes remain on Patrick Mahomes as the Kansas City Chiefs cautiously manage their franchise quarterback through the early stages of camp. Mahomes is recovering from an injury that limited him late in the 2025 season, and while the Chiefs have not placed him on the PUP list, the medical staff has constructed a measured rehabilitation plan. Head coach Andy Reid has emphasized that the priority is Week 1 readiness, not training camp participation. Backup Carson Wentz has taken first-team reps in Mahomes’ absence, and the Chiefs’ preseason approach suggests they are comfortable with Mahomes easing into full practice as August progresses.
Malik Nabers: The Giants’ Biggest Question Mark
The saga of Malik Nabers’ knee continues to dominate headlines at New York Giants camp. What was initially described as a torn ACL sustained last September has proven far more complicated — Nabers also required a full meniscus repair in October and an additional cleanup procedure in the spring to remove inflamed scar tissue. Head coach Jim Harbaugh said Tuesday that he expects Nabers to work his way into camp “one way or another,” and the team chose not to place him on the PUP list, a cautiously optimistic signal. Through 19 career games, Nabers has 127 receptions — the second-most in NFL history behind only Odell Beckham Jr.’s 133 in the same span. The Giants’ offense, built around 2025 first-round quarterback Jaxson Dart, needs its WR1 healthy.
Nick Bosa and Mykel Williams: The 49ers’ Pass Rush Rebuilt
San Francisco’s 2025 season was defined by catastrophic injury luck — the 49ers’ six highest-paid players combined to miss 64 games including the postseason — and the defensive line was hit hardest. Nick Bosa tore his ACL in Week 3, and rookie Mykel Williams followed with the same injury six weeks later. The good news: both players suffered clean tears that have allowed for accelerated rehabilitation. Bosa has been working out at the 49ers’ facility and is expected to participate early in training camp. Williams, who started all nine games before his injury, is similarly on track. With both edge rushers returning, the 49ers’ pass rush — abysmal without them in 2025 — should return to form.
Zach Charbonnet: Seahawks RB on PUP
The defending Super Bowl champion Seattle Seahawks will begin camp without their starting running back. Zach Charbonnet, who tore his ACL in the divisional round of the playoffs in January, has been placed on the physically unable to perform list. His absence opens the door for rookie first-round pick Jadarian Price from Notre Dame, free-agent signing Emanuel Wilson, and holdover George Holani to compete for early-season carries. Super Bowl MVP Kenneth Walker III departed for Kansas City in free agency, making Charbonnet’s recovery timeline one of the most significant storylines in the NFC.
Lions Secondary: Kerby Joseph and Brian Branch
Detroit’s secondary has been decimated. Safety Kerby Joseph is battling a chronic knee condition that first appeared in last year’s training camp and forced him to miss more than half of the 2025 season. Head coach Dan Campbell’s update was blunt: “I honestly do not know” when asked about Joseph’s return. His running mate Brian Branch is in worse shape — a torn Achilles suffered on December 4 means he is unlikely to return before December at the earliest, making him a clear candidate for the PUP list. The Lions, whose defense was obliterated by injuries in 2025, face a major challenge on the back end.
Quarterback Health: Mixed Reports Across the League
Several starting quarterbacks enter camp with significant medical questions. Bo Nix (Broncos) is recovering from a fractured ankle that ended his 2025 season and a follow-up surgery in April to remove bone spurs — but he is expected to start Week 1. Michael Penix Jr. (Falcons) has torn his ACL three times now, twice in college and once in the NFL, and while he aims to participate in camp, his long-term durability remains an open question. Drake Maye (Patriots), who played through a shoulder injury in the AFC Championship Game and Super Bowl, has returned to full participation and looks sharp. The varying timelines illustrate the randomness of NFL health — and why training camp optimism must always be tempered by the reality of what happens when the pads come on.
