A mix-up -- or technicality -- in the Houston-Detroit game involving a challenge flag helped the Texans rally for an overtime win, something that hurt the Ravens on Thanksgiving Day.

Detroit was leading by 10 in the third quarter when Houston's Justin Forsett broke free for an 81-yard touchdown run. Forsett's leg appeared to hit the ground midway through it. Detroit coach Jim Schwartz threw a challenge flag and, according to Associated Press, "negated the automatic review by challenging the play and was called for unsportsmanlike conduct." The penalty was for throwing the challenge flag when the coach isn't allowed to do so.

That's why there was no review of the play, and the touchdown stood. The Texans bounced back and pulled out a 34-31 overtime win.

The victory improved Houston's record to 10-1. A loss would have given the Ravens a chance to tie them for the AFC's top spot with a win Sunday in San Diego. The Texans only have five games left now, which could make it harder for the Ravens to catch and pass them since Houston's got the tie-breaker between the two teams.

The AP story said Schwartz was telling the Lions on the sidelines that the mistakes was his fault, and no matter who's to blame, it handed Houston six points and sparked the comeback. Detroit had a chance to win in overtime but missed a field goal. 

The technicality of this rule in Detroit winds up hurting the Ravens in Baltimore. Detroit still had plenty of time to bounce back and win the game, but the Lions just were not able to do it. Schwartz clearly would like that one back.
