Running back DeMarco Murray contacted Philadelphia Eagles coach Chip Kelly on Wednesday morning to express his interest in playing for the Eagles, ESPN reported Wednesday.

According to the report, a desire to play in Kelly’s spread offense and the presence of quarterback Sam Bradford, who was Murray’s roommate at the University of Oklahoma, were the reasons for his interest.

Whether the Eagles have significant interest in Murray is unclear.

The Eagles needed a replacement for running back LeSean McCoy after he was traded to the Buffalo Bills, but the Eagles signed free-agent running back Ryan Mathews on Wednesday.

Kelly has said he and the Eagles will be financially prudent, so they may not be willing to offer the money Murray is seeking.

Bradford said he has been trying to recruit Murray.

“Absolutely. I’ve been trying my hardest,” Bradford told ESPN. “I’ve called him. I’ve texted him. I’ve done everything. We’ve been in communication. If we can somehow land him, it would be a great pickup. Not only is he a great player, he’s a great person. He’s a really close friend of mine, too. I think he can really help this ball club.”

Murray, 27, led the NFL in rushing last season, gaining 1,845 yards for the Dallas Cowboys, who would like to re-sign him.
