Jimmy Garoppolo’s long recovery begins Thursday.
The 49ers’ franchise quarterback had surgery to repair his torn ACL in his left knee Wednesday morning, Kyle Shanahan said, though the coach wasn’t privy to who performed the surgery.
“I’m not sure,” Shanahan said. “We’ve been going pretty hard here (preparing for the Arizona Cardinals). I’m not sure what time it was this morning, but I know he’s having it sometime today.”
Garoppolo was placed on season-ending injured reserve Sept. 26. He’s expected to be ready in time for next season, though an exact time frame has not been determined.
