Moss shouted at official Jeff Triplette as the Redskins walked to their locker room after a ruling cost them a touchdown.
A number of Redskins players and coaches were around the officials; receiver Pierre Garcon had to be pulled away as well.
The play that started the issue was an apparent touchdown run by Robert Griffin III to end the half. But after the replay, officials ruled that Griffin had lost possession of the ball right before crossing the goal line. Griffin regained it, but lost the ball as he hit the ground, resulting in a touchback.
That led to angry protests from the Redskins, including Moss, drawing an unsportsmanlike conduct penalty and ultimately an ejection. Moss had caught one pass for 18 yards in the first half.
