Gabbert (coach's decision) is inactive for Sunday's Week 15 tilt versus the Falcons, the team's official site reports.
Gabbert will be a somewhat surprising inactive, leaving Christian Ponder to serve as Colin Kaepernick's backup against the Falcons. Given the dire straits the Niners' season is in, head coach Chip Kelly may not hesitate to see what Ponder can do if Kaepernick struggles, or if the game turns into a blowout.
