SANTA CLARA -- Blaine Gabbert got the start once again, and Colin Kaepernick got nowhere in his exhibition-season debut.
Friday night's 21-10 loss to the Green Bay Packers served as the most significant sign yet that Gabbert is winning the 49ers quarterback derby, if he hasn't won it already.After customarily going three-and-out on the opening series, Gabbert engineered a touchdown drive on his next -- and final -- possession. Then came the second quarter for Kaepernick's first — and only -- snaps since November.A half-filled Levi's Stadium greeted Kaepernick's debut with loud cheers. But there wasn't much more to cheer from old No.
