The Dallas Cowboys staged a fourth-quarter comeback to beat the Cincinnati Bengals by a single point.
The Cowboys held a moment of silence in honour of practice squad member Jerry Brown before the game, after he was killed in a car crash on Saturday.
A closely-matched opening two quarters saw the Bengals take a narrow lead at half-time.
Two field goals from Josh Brown, who signed for Cincinnati on Thursday following an injury to Mike Nugent, saws the Bengals go into the final 15 minutes nine points ahead.
Quarterback Tony Romo threw a 27-yard pass to Dez Bryant for a touchdown to leave Dallas just two points down, before Dan Bailey added a field goal in the closing minutes of the game.
The 19-20 loss damages the Bengals' chances of securing a playoff wildcard place, as they remain third in the AFC North, while the Cowboys remain in the hunt for the NFC East title.
