Though Bucs RB Doug Martin said he doesn't need to play Saturday against the Dolphins in order to be ready for the regular season, he wouldn't mind taking a few snaps. "It's up to the coaches," he said. Martin has just three carries in two preseason games and left last week's 25-21 loss to the Patriots after taking a shot to the head during pass protection. Martin said his concussion tests were negative and he is 100 percent healthy and has practiced all week. However, Martin said he'd understand if the coaches hold him out as a precaution. "I'm not sure what we're going to do with Doug right now," coach Greg Schiano said Thursday. Whether Martin plays or not, the three candidates to be his backup — Brian Leonard, Peyton Hillis and Mike James — will play "a bunch," Schiano said. Source: Tampa Bay Times
