Texans score disputed TD against Lions

DETROIT (AP) Houston's Justin Forsett scored on an 81-yard run in the third quarter Thursday against the Detroit Lions, even though replays clearly showed his knee touching the ground around his own 25-yard-line.

Detroit coach Jim Schwartz probably helped the touchdown stand by throwing his challenge flag.

The TD counted and Detroit was called for unsportsmanlike conduct. A Lions spokesman said a coach is not allowed to challenge scoring plays, which are automatically reviewed. If a coach does throw a challenge flag, the automatic review is negated.

Schwartz was seen tapping his chest on the sideline, saying ``it's on me.''

The irate crowd at Detroit's Ford Field kept booing the call for several minutes, even as the game continued.
