The Houston Texans took advantage of a big mistake by Detroit Lions coach Jim Schwartz.
Shayne Graham's 32-yard field goal with 2:21 left overtime lifted Houston to a 34-31 win over Detroit on Thursday after Schwartz broke an NFL rule on a scoring play.
Detroit kicker Jason Hanson had a chance to get 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.
''It's on me,'' Schwartz said to his assistant coaches and players on the sideline as he tapped his chest. ''It's on me.''
Yes, it was.
That touchdown pulled Houston within three points counted and Schwartz was called for unsportsmanlike conduct.
