Oakland Raiders coach Jack Del Rio said he expects Lavatius Murray and Trent Richardson to compete for the starting tailback job.

With Maurice Jones-Drew retiring and Darren McFadden going to Dallas, Murray is the incumbent on an offense that ranked dead last in the NFL in the run game. Murray has just 82 career carries and two touchdowns.

Richardson, the former No. 3 overall pick who floundered with Cleveland and Indianapolis, was signed to a two-year deal with Oakland last week.

"I think it will be a competitive situation," Del Rio said.

Del Rio likes Richardson's potential.

"What I saw when we brought him in and talked to him was a young man that was hungry to kind of leave that portion of his career behind him and start fresh," Del Rio said. "My challenge to him was, 'Look, I don't want you to worry about anything other than coming in here and competing your butt off every day. Come in here and be a great teammate. Come in here and find a role on special teams. Come in here and just grind every day with the hunger you had as a freshman at Alabama.'"
