Graham the hero for Texans
Shayne Graham kicked a 32-yard field goal with less than three minutes left in overtime to give Houston a dramatic 34-31 win at Detroit.
Detroit kicker Jason Hanson had the chance to win a rollercoaster game on the fifth possession of overtime, but his 47-yard effort hit the right upright.
Despite such a thrilling climax, the biggest talking point of the game was a costly blunder from Lions' coach Jim Schwartz.
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 by contact near midfield, but Schwartz negated the automatic review by challenging the play and was penalised for unsportsmanlike conduct.
The Texans, who improved to 10-1 at the top of the AFC South, took their first lead of the contest when Graham made up for missing a field goal earlier in an overtime period filled with turnovers.
They have won five straight and two in a row in OT, and if a handful of teams lose they might be in the play-offs by the time they get back on the practice field after a long weekend.
