Dolphins offensive tackle Jonathan Martin recently checked himself into a South Florida hospital to be treated for emotional distress after leaving the team last week, ESPN's Chris Mortensen reports. After a brief stay, Martin reportedly returned to California with his parents.

Dolphins coach Joe Philbin visited Martin at the hospital, and the Dolphins reportedly arranged for his parents' travel to South Florida.

The specific treatment of Martin's emotional condition was not disclosed, but sources say it was related to his belief that he had been targeted during a sustained level of harassment from teammates, including suspended guard Richie Incognito.

Martin did not disclose to Philbin any specific incident of harassment or bullying when the coach made the hospital visit, sources said.

Martin remains in California, preparing a detailed document for his cooperation with a league investigation into a string of alleged multiple incidents he says led to his emotional distress and exit from the team, sources said.
