Romo wasn't done doling out points for the opposing team. After Carpenter's touchdown, Houston wrestled the ball from Laurent Robinson and dashed down the sideline to cut the Cowboys' lead to 10 points.

Bobby Carpenter was a groomsman at Tony Romo's wedding in May, but it was Romo who served up a present Sunday. Down 24 points in the third quarter, Carpenter sparked the Lions' comeback by grabbing a pass intended for Dez Bryant and returning it for a score.
