When Raiders RB Darren McFadden does return, it's become clear he'll have to wait his turn.
"(Rashad Jennings has) been a guy we've called on to come in and run the ball and he's done a great job at it,'' Allen said. "As he continues to run the ball like he's doing, he's going to continue to get opportunities to run the ball.''
Jennings signed as an unrestricted free agent after averaging 2.8 yards per carry in Jacksonville last season. Jennings has 340 yards on 57 carries, averaging 6.0 yards per carry in his last three games. He is second to Terrelle Pryor in rushing with 480 yards. He has a couple of very favorable matchups in Weeks 12 and 13 with Tennessee and Dallas on the schedule.
