Shayne Graham's 32-yard field goal with 2:21 left overtime lifted the Houston Texans to a 34-31 win over Detroit on Thursday after the Lions' coach made a costly mistake in regulation.
Detroit kicker Jason Hanson had a chance to get Jim Schwartz off the hook, but his 47-yard field goal attempt on the fifth possession of the extra period hit the right upright.
Schwartz threw a challenge flag when Houston's Justin Forsett scored on an 81-yard touchdown run in the third quarter. Replays showed Forsett was down near midfield, but Schwartz negated the automatic review by challenging the play and was called for unsportsmanlike conduct.
