Niners Edge Nick Bosa injured a calf in practice this week and is expected to miss "a few weeks," according to NFL Network's Ian Rapoport. The team reportedly hasn't decided yet whether to place Bosa on IR.
Niners Edge Nick Bosa got his first full practice in Wednesday since the right ACL tear that ended his 2025 season in Week 3. He then traveled with the team to Australia for next Wednesday's season opener against the Rams and says he hopes to play in it. But there's reason for IDP managers to maintain some skepticism.
It’s no surprise that 49ers Edge Nick Bosa isn’t fully participating in his team’s OTAs this week. The veteran’s working back from a right ACL tear he suffered in September. But Bosa told reporters Thursday that he has a shot to be ready for the start of training camp “or soon after, barring any setbacks,” according to ESPN’s Nick Wagoner. Bosa previously tore his right ACL as a high school senior in 2015. He tore the left one in Week 2 of 2020, as a member of the Niners.
