Gabbert completed six of nine passes for 69 yards in Saturday's preseason game against the Broncos.
With Colin Kaepernick (shoulder) still unavailable, Gabbert played the first three series of Saturday's game, producing seven points before handing the ball over to Jeff Driskel. While Kaepernick seems to be making progress and could be available for the final two preseason games, recent reports suggest the starting job is Gabbert's to lose.
