Sports Seriously

The San Francisco 49ers can’t seem to shake persistent injuries amid the team’s 3-0 start. On Monday, the team learned of its mostly costly personnel loss yet.

Defensive end Nick Bosa suffered a torn anterior cruciate ligament in Sunday’s 16-15 win against the Arizona Cardinals and will miss the rest of the season, the team confirmed Monday.

Bosa exited the game late in the first quarter after being knocked to the ground on a pass rush. He gave a thumbs down as he headed to the locker room and did not return to the game.

49ers coach Kyle Shanahan said after Sunday’s game that initial tests did not indicate Bosa had suffered a torn ACL but that more testing would be required. An MRI eventually revealed the extent of the damage.

“It’s just how those things happen a lot, especially with ACLs,” Shanahan said Monday. “They happen on air the majority of the time, and I know it was his right leg and he just got it caught right there and it went right away.”

Bosa previously suffered a torn ACL in Week 2 of the 2020 season. He returned the following year to earn his second of five career Pro Bowl berths, and he was named the NFL’s Defensive Player of the Year in 2022.

The 49ers already have suffered significant injury hits to quarterback Brock Purdy, who missed his second consecutive start Sunday while dealing with shoulder and toe injuries, as well as tight end George Kittle, who landed on injured reserve with a hamstring injury suffered in Week 1. Wide receiver Jauan Jennings also sat out Sunday due to shoulder and ankle injuries.
