Dolphins starting right tackle Jonathan Martin has walked out on the team.

Jay Glazer of FOX Sports reports that Martin has “gone AWOL from the team the last couple days.”

Glazer said Martin had an incident in the team cafeteria this week in which teammates jokingly said they wouldn’t sit with him, and that Martin’s reaction to the joke was that he “flipped out, smashed a food tray on the ground, took off, and they haven’t seen him since.”

The Dolphins have listed Martin as doubtful for Thursday night’s game against the Bengals with an “illness” but have refused to divulge anything else about his status. Glazer also reported that Martin has gone into a treatment facility, but it is not clear what type of treatment Martin is receiving. Glazer said rumors that Martin had a confrontation with Dolphins offensive coordinator Mike Sherman are incorrect.
