St. Louis, MO (Sports Network) - St. Louis Rams wide receiver Danny Amendola left Thursday night's game against the Arizona Cardinals in the second quarter with a shoulder injury.
Amendola suffered the injury while attempting to make a diving grab down the sideline.
The play was initially called a 22-yard reception, but an Arizona challenge overturned the call as it showed the ball hit the ground before the receiver gained full control.
He then angrily threw his helmet at a wall while he was being walked to the locker room with team trainers.
Amendola had one catch for 44 yards in the contest but is questionable to return.
The Rams suffered another injury soon after when safety Quintin Mikell was kneed in the back of the head by his own teammate in a pile.
He looked to be knocked out on the play and did walk off the field under his own power, but is also listed as questionable to return.
