The most significant play of the fourth quarter occurred with 1:18 left to play after Josh Morgan caught a pass from Robert Griffin III and advanced to the 29-yard line, picking up 7 yards and leaving the Redskins with a 4th-and-1 situation.
If the Redskins had been able to try a potential game-tying field goal attempt, Billy Cundiff would have had a 46-yard try facing him. But he never got the chance.
That's because after Cortland Finnegan shoved Morgan following the whistle, Morgan fired the ball straight into Finnegan's torso.
The officials called unsportsmanlike conduct on the Redskins receiver, a penalty which pushed the Redskins back to the St. Louis 44. Cundiff's resulting 62-yard try was short, and well to the right.
Two kneel-downs later, the Redskins had suffered their first loss of the season.
