The preseason is underway, and NFL stars’ training camp injuries have already become one of the defining storylines of the summer. One situation has already turned into a confirmed season-ender, while several others are trending in more encouraging directions than they first appeared just days ago.
NFL Stars Training Camp Injuries: Jalon Walker Jr.’s Season Is Officially Over
The Atlanta Falcons’ biggest camp blow is now fully confirmed. The Falcons announced that imaging confirmed a torn ACL for second-year pass rusher Jalon Walker. He was carted off the field during a non-padded practice and will undergo season-ending surgery. The loss is magnified by Atlanta’s already thin edge rusher depth, compounded by first-round pick James Pearce Jr. facing a potential suspension tied to an off-field legal matter. Walker recorded 5.5 sacks as a rookie and was expected to take a significant step forward in Year 2.

NFL Stars Training Camp Injuries: Mike Evans’ Quad Strain Trending Positive
The San Francisco 49ers’ big offseason addition, Mike Evans, is dealing with a quad injury, but the outlook has improved since it was first reported. Multiple team sources now believe the issue could resolve relatively quickly, and it isn’t considered a long-term concern. Evans has watched recent practices in street clothes while still doing light receiver work during special-team periods. This is an encouraging sign for a 49ers offense counting on him early in the season.
NFL Stars Training Camp Injuries: Nick Bosa’s Recovery Looks Ahead Of Schedule
San Francisco’s star pass rusher, Nick Bosa, continues working back from last season’s torn ACL, and the updates keep getting better. Bosa isn’t on the PUP list and has begun individual and one-on-one pass-rush drills. Left tackle Trent Williams said he can’t even tell Bosa suffered a major injury, adding that Bosa looks better than he did before getting hurt. While full team drills are still being phased in, the 49ers appear on track to have him ready for Week 1.
NFL Stars Training Camp Injuries: Jahmyr Gibbs’ Situation Is More Complicated Than It Looks
Detroit’s star running back, Jahmyr Gibbs, has been absent from practice, but the full picture involves more than just health. Reports indicate that Gibbs’ absence is partly tied to contract negotiations. Bijan Robinson recently signed a new extension in Atlanta that could influence Gibbs’ market value. He pushed back on the idea that a new deal is required for him to practice, but he also admitted he doesn’t know when he’ll return to the Lions, leaving real uncertainty either way.
NFL Stars Training Camp Injuries: Matthew Stafford’s Back Is Stacking Good Days
The Los Angeles Rams’ championship hopes still hinge on Matthew Stafford’s health, but recent updates offer real encouragement. After sitting out much of early camp with what’s been described as a degenerative back issue, Stafford has now been a full participant in back-to-back practices. Coach Sean McVay said he was encouraged and hopeful Stafford can continue “stacking days.” The Rams still haven’t formally committed to him being ready for Week 1, keeping this one of the season’s most closely watched recoveries.

What These Injuries Mean Going Forward
Reviewing the five situations, only Walker’s has resulted in a confirmed season-ending outcome so far, while Evans, Bosa, and Stafford all appear to be trending in the right direction. Gibbs remains the most unresolved case, tangled between health and contract questions that likely won’t clear up until closer to Week 1.
For Atlanta, Walker’s loss forces an already thin edge rusher room to lean on veterans like Samson Ebukam and Azeez Ojulari while hoping James Pearce Jr. avoids a suspension of his own. For San Francisco, the picture looks considerably brighter than it did a week ago, with both Evans and Bosa trending toward availability for the regular season rather than extended absences.
Los Angeles’ entire outlook still hinges on Stafford stringing together enough healthy practice days to enter the season without lingering restrictions, even as McVay’s recent comments offer real reason for optimism. Detroit’s situation with Gibbs may resolve itself through a new contract rather than a medical update, which would make it one of the more unusual storylines of the summer.
