Joey Bosa Injury Bombshell: Chargers Star’s 2025 Season Status Revealed

ORCHARD PARK, N.Y.—Buffalo Bills edge rusher Joey Bosa is expected to miss the remainder of organized team activities and minicamp after straining his right calf during individual drills on Monday, head coach Sean McDermott confirmed Tuesday morning. The five-time Pro Bowler will spend the next four to six weeks rehabbing, with the franchise “optimistic” he will be cleared when players report for training camp in late July. Bosa, 29, signed a one-year, $12.6 million contract with Buffalo on March 11 after the Chargers released him in a salary-cap move that ended his nine-season tenure in Southern California. General manager Brandon Beane targeted the veteran pass rusher to bolster a defense that finished 28th in sacks per drop-back last year and lost Leonard Floyd in free agency. According to multiple team sources, Bosa grabbed the back of his leg while exploding off the line during a routine get-off period and did not participate in 11-on-11 work. An MRI later revealed a Grade 1 calf strain, the mildest classification. “If this had happened in November, he might try to push through,” McDermott said. “But in May, there’s no reason to risk a setback. We need him healthy in September.” The setback renews durability concerns that shadowed Bosa’s final seasons with the Chargers, when groin and foot issues limited him to 14 games over the last two years. Still, Buffalo’s medical staff believes the current injury is unrelated and view it as “precautionary.” Bosa has already begun pool workouts and is expected to transition to on-field agility by mid-June, per a source familiar with his rehab plan. While Bosa rehabs, 2021 first-rounder Gregory Rousseau and veteran A.J. Epenesa will split first-team reps opposite Von Miller. Defensive coordinator Bobby Babich noted the temporary shuffle could accelerate Rousseau’s development as an every-down edge. “Greg hit 55 pressures last year; we think he can take another leap,” Babich said. “Working full-time with Von in OTAs is only going to sharpen his game.” Fantasy football managers shouldn’t panic, but IDP league owners may want to monitor training-camp participation closely. Even with a late-July return, Bosa could face a limited pitch count in preseason games. Historically, calf strains carry a 6–8 percent recurrence rate when players are rushed back within four weeks, according to data from the American Journal of Sports Medicine. For Bills fans, the calendar provides comfort: the team’s regular-season opener is still 15 weeks away. If Bosa meets his projected timeline, he will have roughly five weeks of full practice before Week 1. “That’s plenty of runway,” Miller said. “We’ll get the NASCAR package revved up just in time.” Key takeaways for searchers: • Joey Bosa injury update: Grade 1 calf strain, out until training camp. • Impact on Bills OTAs and defensive depth chart. • Timetable and risk of re-injury heading into 2025 NFL season.
