Jonathan Martin, the offensive lineman who became a household name when he left the Miami Dolphins amid bullying in the locker room, has decided to retire.

Martin will file his retirement papers, in part because of a back injury that would have forced him to miss this season, according to Ian Rapoport of NFL Network.

The 25-year-old Martin was a second-round draft pick of the Dolphins in 2012 and started all 16 games for them as a rookie and seven more games in 2013 before the bullying incident, which caused a much-publicized investigation into the Dolphins’ locker room culture. Last year Martin started nine games for the 49ers, and this year he was claimed by the Panthers after the 49ers cut him.

Now Martin will walk away from the game, and begin a new chapter in his life.
