The San Francisco 49ers signed quarterback Tom Savage on Tuesday, making room on the roster by releasing tight end Cole Wick.The team worked out Savage and other quarterbacks after Jimmy Garoppolo went down with a torn ACL in Week 3, but no signing was made until Tuesday.Nick Mullens has been serving as the backup to C.J. Beathard, but head coach Kyle Shanahan said the team hoped to add a third QB.

In 13 career appearances, he has 2,000 passing yards on a 57.5 percent completion rate with five touchdowns and seven interceptions.Wick played in five games for the 49ers this season, logging one target on 11 offensive snaps while mostly playing special teams (70 snaps).
