The Facts: Gabbert, who saw action in just one game last season as Colin Kaepernick's backup, is reportedly coming back to the 49ers. Gabbert is "staying in San Francisco," a source told ESPN.

Diehards Line: Currently, Kaepernick is the only quarterback on the 49ers' roster. The 49ers were believed to be interested in signing free-agent Jake Locker, but Locker announced his retirement on Tuesday after just four NFL seasons. The 49ers originally acquired Gabbert in a trade with the Jacksonville Jaguars last year on the first day of the league year. Gabbert's only action during the regular season came in a 42-17 loss to the Denver Broncos. He completed 3 of 7 pass attempts for 38 yards and a touchdown.
