The Tampa Bay Buccaneers are fielding offers for Doug Martin, according to sources.

Teams have already approached Tampa Bay about Martin, and some around the league believe that the Buccaneers would be willing to deal him for the right price before Tuesday's 4 p.m. ET trade deadline, according to sources.

Martin is averaging just 2.9 yards per carry this season, rushing for 139 yards and a touchdown. Martin was a breakout running back in his rookie season in 2012 but has since been limited by injuries.
