The Miami Dolphins have placed Jonathan Martin, who has been away from the team for several weeks in the midst of a bullying scandal involving teammate Richie Incognito, on the non-football injury list.

By placing Martin on the non-football injury list, the second-year offensive lineman is ineligible to play again this season and no longer counts toward the Dolphins' 53-man roster.

The Dolphins signed safety D.J. Campbell, who was previously on both the active roster and practice squad, with the open spot created by Martin.

From a financial standpoint, the Dolphins have the flexibility to choose how much of Martin's base salary he will receive for the rest of the season. The 24-year old signed a four-year rookie contract that includes a base salary of $607,466 for the 2013 season, and the Dolphins can choose to pay as little as none or the balance of his base salary for the remaining portion of the season.
