After the 49ers’ fifth straight loss Sunday in Buffalo, Chip Kelly wouldn’t commit to Colin Kaepernick as the starting quarterback for the team’s next game against the Tampa Bay Buccaneers.

“We’ll see,” Kelly said afterwards, when asked if Kaepernick would start next week.

Kaepernick completed 13 of 29 for 187 yards with a touchdown and no interceptions. He had a passer rating of 77.8 making his first start since last November.

And after completing eight of 11 in the first half with a 113.8 passer rating, he completed just five of 18 for 52 yards in the second for a rating of 39.6.

The 49ers were outscored 28-3 after halftime.

“I thought (Kaepernick) was OK. There were some positives that you can really build on with him,” Kelly said. “I thought he extended some drives, keeping plays alive with his legs. Obviously he did a good job. It was a pretty good situation in terms of him running the football. But overall, as a group, we need to run the ball as a group better. We need to better in the passing game.”

Kelly was similarly non-committal about his starting quarterback after the team’s previous loss to the Cardinals before eventually making the switch to Kaepernick from Blaine Gabbert.

But Kelly was quick to note Sunday the entire offense needs to improve.

“We got to be better overall,” Kelly said. “It’s not just the quarterback. It’s everybody on the offensive side of the ball. I thought he made some plays with his legs today.”

Kaepernick led the 49ers with 66 yards rushing, including an impressive 29-yard scamper. He also avoided a safety in the third quarter and turned it into a first-down run.

The highlight of Kaepernick’s day came when he hit Torrey Smith for a 53-yard touchdown early in the second quarter giving San Francisco a 10-7 lead. Otherwise, however, Kaepernick struggled with his accuracy on throws deep down field.

“In the first half, I thought we were in a decent rhythm, did some nice things. But we got to be able to sustain that the whole game,” said Kelly.
