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.

Mike Pouncey was served a subpoena as he exited the Miami Dolphins' locker room following their 27-17 loss to the New England Patriots.

The subpoena is related to an investigation into Aaron Hernandez, who is a close friend and college roommate of Pouncey.

Sports Illustrated claims sources indicated that Pouncey's subpoena has to do with an investigation centering on Hernandez's potential involvement in interstate gun trafficking, not the pending murder trial.

The Miami Dolphins have acquired Bryant McKinnie in a trade with the Baltimore Ravens.

The Dolphins badly needed to improve their offensive line to give Ryan Tannehill more time.
