ProFootballDoc Breaks Down Jimmy Garoppolo's Injury

Sunday, Jimmy Garoppolo re-injured his ankle against the Seahawks. Garoppolo left the game in the third quarter and did not return.

This is the same ankle that kept Garoppolo out of two games this season.

OutKick's David Chao, MD, ProFootballDoc, breaks down the injury:

"This could easily cost him some time."

The 49ers have a short week. Thursday night, they host the Green Bay Packers.
