San Francisco pass rusher Nick Bosa and quarterback Jimmy Garoppolo were among several key players who sustained injuries Sunday during the 49ers’ 31-13 win against the New York Jets.

Coach Kyle Shanahan told reporters after the game that Bosa likely has a torn ACL but needs further testing.

Bosa was carted off the field in the first quarter with an injury to his left knee. It occurred at the 6:45 mark as Jets running back Frank Gore ran for 4 yards and Bosa got tangled up as he was engaged with a blocker.

Two plays later, defensive lineman Solomon Thomas also suffered a left knee injury and was carted off. Shanahan said he was hopeful that Thomas’ injury was not as severe as Bosa’s.

Garoppolo was ruled out at halftime with a high ankle sprain and was replaced by Nick Mullens to start the second half. Garoppolo completed 14 of 16 passes for 131 yards and two touchdowns as the 49ers took a 21-3 lead into intermission.

Running back Raheem Mostert also was ruled out for the second half with a knee injury. Mostert, who broke off an 80-yard touchdown run on the game’s first play from scrimmage, had eight carries for 92 yards and two catches for 15 yards.

The 49ers believe Mostert suffered a mild sprain of the MCL. An MRI will determine the severity of the injury.

San Francisco already was playing on defense without pass rusher Dee Ford (neck) and cornerback Richard Sherman (calf), but an extended loss of Bosa would be significant for the 49ers. The Defensive Rookie of the Year in 2019, Bosa had nine sacks and 25 quarterback hits last season.

The offense was already missing All-Pro tight end George Kittle (knee sprain) and receiver Deebo Samuel (foot).
