ARLINGTON, Texas — Bradford left the game with a few seconds left in the first half after getting hit hard and landing on his right shoulder.

It was announced during halftime he suffered an AC joint sprain, which is a sprain of the two bones attached at the acromioclavicular ligament.

The amount of recovery time and treatment varies on the severity of the injury.

Bradford will not return for the game and backup freshman quarterback Landry Jones will take his place on the field.
