After Sunday’s game, 49ers HC Kyle Shanahan told reporters after the game that they were worried that Garoppolo had a torn ACL.
“With Jimmy, we’re fearing ACL,” Shanahan said. “We’ll find out tomorrow. I haven’t had a chance to talk to him yet. I feel for him.”
Garoppolo suffered the injury during the fourth quarter of Sunday’s game while trying to stay in bounds and pick up more yardage. He was later taken to the locker room on a cart with a left knee for further evaluation.
You can expect the 49ers to place him on injured reserve in the coming days and add someone to their roster.
Garoppolo, 26, is a former second-round pick of the Patriots back in 2014. The Patriots traded him to the 49ers at this last year’s deadline in return for a 2018 second-round pick.
Garoppolo was in line to be an unrestricted free agent when the 49ers signed him to a five-year, $137.5 million contract during the offseason.
In 2018, Garoppolo appeared in three games for the 49ers and completed 59.6 percent of his passes for 718 yards, five touchdowns and three interceptions. He also rushed for 33 yards.
