Oakland Raiders running back Darren McFadden suffered a hamstring injury in the 4th quarter of the Raiders loss to the Texans after a 23 yard run. "I was trying to go for another gear and I just pulled up," he said. "I tried to get out (of bounds) first because I didn't want to pull it too fast." McFadden will see trainers today and "take it day to day." He missed most of training camp with a tight left hamstring. Source: San Francisco Chronicle
