Derek Carr was frustrated after the Las Vegas Raiders dropped their second-straight game on Sunday afternoon.

"I'm sick of losing," said Carr, who became the team's all-time leader in touchdown passes in their 30-23 loss to the Buffalo Bills.

The quarterback has a 41-57 record as a starter.

"I'm sick of losing," Carr said. "I'm sick of working as hard as I do, and as we do, and going out there and losing. I mean, it sucks. Enough is enough.

"The things that are hurting us in these close games is not them; it's us. That's the hard part to swallow."
