Buffalo Bills head coach Sean McDermott announced Tuesday that pass-rusher Joey Bosa pulled his calf and will likely be sidelined until training camp, according to NFL Network's Ian Rapoport.

The Bills inked Bosa to a one-year, $12.6-million contract that contained $12 million in guaranteed money this offseason.

The Los Angeles Chargers released the 29-year-old this year after nine seasons.

Bosa has struggled with injuries over his career. He has played a combined 28 games over the last three years and has only played a full season in two of his nine campaigns.

The veteran recorded five sacks in 2024. He hasn't exceeded 10 sacks since 2021.

Running back James Cook did not attend voluntary organized team activities, McDermott said, according to ESPN's Alaina Getzenberg. Cook wants a new contract and is entering the final season of his rookie deal.

McDermott added that he's staying in touch with Cook and that the running back "will be here when he's ready to be here."
