Rookie running back Doug Martin didn’t start Friday’s game, but after LeGarrette Blount left in the second quarter with an apparent groin injury, Tampa Bay may have to lean a little heavier on the 5-foot-9, 223-pound former Boise State star.

Martin, alternating series with Blount, racked up 23 yards on seven carries and had a 15-yard-run in the first quarter brought back by a holding call in the Buccaneers’ 30-7 loss to Tennessee.

Coach Greg Schiano has said the competition between Martin and Blount would be fluid, and if one separated himself, he could earn more touches. Martin outshined Blount (11 yards, eight carries) Friday.

• Quarterback Kellen Moore had a better performance in his second preseason game with the Lions, a 27-12 win over Baltimore. After entering the game in the latter part of the third quarter, Moore completed 10-of-15 passes for 96 yards. His best drive came early in the fourth quarter, when Moore led Detroit on a 12-play, 57-yard drive that ended with a field goal. Moore was 4-for-6 for 40 passing yards on the drive.

• In the same game, Lions wide receiver Titus Young had a 24-yard touchdown catch. Dave Birkett of the Detroit Free Press said of Young's performance Friday, his first in the preseason: "Young caught just one pass, broke a tackle and dove into the end zone for the Lions’ second touchdown. He has looked good all summer and will be a big weapon this year."
