Miami Dolphins offensive tackle Jonathan Martin recently checked himself into a South Florida hospital to be treated for emotional distress that led the second-year player to leave the team last week, league sources told ESPN.
Martin was visited at the hospital by Dolphins coach Joe Philbin, and the organization arranged for his parents to travel to South Florida, the sources said.
Martin's hospital stay was brief before he returned to California with his parents, according to sources.
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.
