The San Francisco 49ers will start Blaine Gabbert in Week 1 at quarterback instead of Colin Kaepernick.

Kaepernick was behind in the competition due to missing the first two preseason games.

“I think Blaine reacted the way he reacts every day,” Chip Kelly said. “It was just matter-of-fact for him — ‘Let’s go to work.’”

Kelly said Kaepernick will back up Gabbert in Week 1 and Christian Ponder will be inactive.
