Sources: 49ers' Jimmy Garoppolo might be OK for playoffs play Could Jimmy G make a postseason return? (1:17) Dan Orlovsky and Ryan Clark wonder if the 49ers would re-insert Jimmy Garoppolo deep in the playoffs if Brock Purdy leads them there. (1:17) 4:34 PM ET ESPN San Francisco 49ers quarterback Jimmy Garoppolo 's broken foot will not require surgery and there is a chance he could return this season, sources told ESPN's Adam Schefter. Doctors concluded Tuesday that Garoppolo did not suffer a Lisfranc injury to his broken left foot, and if rehab goes smoothly, he could have a chance to return in 7-8 weeks, making him a potential playoff contributor, sources said. Garoppolo was injured eight plays into Sunday's win over the Miami Dolphins . He had started every game since Trey Lance was lost for the season to an ankle injury in September. Garoppolo has gone 7-3 as a starter this season. The Niners will now rely on rookie Brock Purdy , who went 25-of-37 for 210 yards and two scores with an interception for a passer rating of 88.8 in relief of Garoppolo on Sunday.
