The San Francisco 49ers will at least consider benching Blaine Gabbert in favor of Colin Kaepernick after losing to the Arizona Cardinals on Thursday night.

"I don't think anybody played well on offense," Chip Kelly said. "Nobody did."

The 49ers have 10 days to decide before they face the Buffalo Bills in Week 6.

"I think we're going to look at everything," Kelly said. "We are 1-4, we have got to make sure we're going out there and giving us the best chance to win so we're going to look at everything."
