The Raiders will go into training camp with a potential position battle at No. 2 running back behind Darren McFadden, which is an important role given McFadden's injury history.

The main participants will be rookie Latavius Murray and Rashad Jennings, but fullback Marcel Reece is also in the mix.

According to Comcast Sports Net, Murray might have the lead going into training camp because at 223 pounds, Murray fits the Raiders scheme the best. Murray missed part of the offseason program with a foot injury, so he must make the most of training camp and his preseason carries to earn the No. 2 spot.

Jennings came to Oakland via free agency from Jacksonville, where he averaged 2.8 yards per carry and struggled filling in for Maurice Jones-Drew (foot) last season.

Reece filled in for McFadden last year, but the Raiders seem intent on keeping him at fullback. Still, if McFadden gets hurt this season, Reece could still play a prominent role.
