San Francisco 49ers star Nick Bosa has suffered a torn anterior cruciate ligament (ACL) and will miss the rest of the NFL season.

Bosa, 22, was hurt during the 49ers’ costly 31-13 win over the New York Jets in the NFL on Sunday.

While the 49ers were initially waiting for scans for Bosa, the team later confirmed the 2019 Pro Bowl had torn his ACL.

“An MRI confirmed Nick Bosa suffered a torn ACL in yesterday’s game,” they wrote on Twitter.

“We’re all wishing @nbsmallerbear a speedy recovery.”

Bosa, quarterback Jimmy Garoppolo and running back Raheem Mostert were the key players hurt in the 49ers’ win.

In his rookie year in the NFL, Bosa had 47 tackles, nine sacks and an interception as the 49ers reached the Super Bowl before losing to the Kansas City Chiefs.

Bosa was named the NFL Defensive Rookie of the Year.

The 49ers are 1-1 to begin the 2020 season and face the New York Giants on Sunday.
