Jonathan Martin has left the Miami Dolphins following an "emotional breakdown," according to a teammate.
Jay Glazer reported that Martin was the victim of a prank at the cafeteria, becoming enraged enough to "smash his food tray on the ground."
Martin sought treatment at a local hospital and has since left to spend time with his family.
Martin began the season as the Dolphins' replacement for Jake Long at left tackle and was moved to right tackle after the team acquired Bryant McKinnie.
