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.
