The Tampa Bay Buccaneers’ starting running back Monday night against the Atlanta Falcons will be Peyton Barber.

Doug Martin is inactive Monday night for an unspecified violation of team rules, the team said.

Martin has started eight of the nine games he has played in this season, but he has struggled, averaging just 3.1 yards per carry.

He was benched for the second half after he lost a fumble in the Buccaneers’ 24-21 loss to the Detroit Lions in Week 14. He finished with 10 carries for 26 yards and a touchdown. Barber had 12 carries for 58 yards in the loss.

Barber has appeared in all 13 of the Buccaneers’ games this season and is averaging 3.8 yards per carry. He got his only start this season in Week 13 against the Packers, when Martin was out with a concussion. In that game, he rushed for 102 yards on 23 carries.

Martin, a two-time Pro Bowl selection, has 402 yards on 129 carries this season. He has three rushing touchdowns.

Barber, in his second season, has 248 yards on 65 carries. He has rushed for two scores.
