Alex Smith threw two touchdown passes and the Chiefs held on for a 23-17 victory Sunday to give them a franchise-best 10 straight wins entering the postseason.

The Chiefs will head to Houston as the fifth seed in the playoffs.

The Chiefs (11-5) are somehow in the dance after a 1-5 start.

The Raiders (7-9), who accounted for two of those victories, had the ball with 1:34 left. But Derek Carr was sacked for the sixth time, and the clock expired before they came close to a go-ahead touchdown.
