Dolphins offensive tackle Jonathan Martin wants to play football again but feels he can’t do it in Miami and is likely done with football for the season, a source close to the player told ESPN’s Lisa Salters.
The 24-year-old Martin is relieved to be away from the team because the last season and a half was unbearable for him, the source told ESPN.
Martin hated being picked on so he tried to befriend teammates, according to the source.
Martin is expected to give his side eventually, but he wanted to create some time and space before he does, the source said. He is with his family and is receiving medical treatment for an undisclosed reason, according to the source.Dolphins' Martin Wants To Play But Can't by Sports Talk Florida
