Martin tore his labrum in Week 7 against the Atlanta Falcons. As noted by Rick Stroud of the Tampa Bay Times, he'll be out for the foreseeable future, but the team hasn't yet decided whether it will place him on injured reserve:
The Bucs claimed Rainey off waivers from the Cleveland Browns and released receiver Skye Dawson to make room for him on the roster, as Stroud reported:
Rainey wasn't likely brought to Tampa Bay to become the team's starter, however. That responsibility will certainly fall to rookie Mike James, who filled in for Martin Sunday and performed fairly well under the circumstances.
Brad Evans of Yahoo! Sports expects James to be an 18-20 touch player for the Bucs, meaning there won't be much action for Rainey:
Speaking of Rainey, many people are likely wondering who he is.
The second-year player went undrafted out of Western Kentucky in 2012 and ended up with the Browns. He didn't see the field as a rookie, and he had been used sparingly by Cleveland this season, totaling 53 yards on 17 touches.
The Buccaneers almost certainly brought Rainey onto the roster to be the third running back behind James and veteran Brian Leonard. Speedster Jeff Demps is also on the roster, but he's not an effective between-the-tackles back.
Rainey will be stuck behind Leonard and James, and there's a good chance he won't see any action at all in Week 8 against the Carolina Panthers.
Feel free to add Rainey to your watch list as the situation in the Bucs' backfield develops, but for now he's not worthy of a roster spot in fantasy football.
