Jimmy Garoppolo throws TD pass after replacing injured Trey Lance

Jimmy Garoppolo came off the bench and was on target for the 49ers

The San Francisco 49ers’ decision to keep Jimmy Garoppolo as a backup has proven brilliant.

Trey Lance was carted off with a right ankle injury in the first quarter of Sunday’s game with the Seattle Seahawks.

On came the veteran Garoppolo and he completed his first four passes, one going for a touchdown.

George Kittle was out, too, so Garoppolo went to Ross Dwelley on a play that was good for 38 yards and gave San Francisco a 13-0 lead early in the second quarter.
