Philadelphia Eagles running back DeMarco Murray has admitted that he is still unsure how he and Ryan Matthews will split plays this season.

Murray joined the Eagles from the Dallas Cowboys in the summer after scoring 13 touchdowns this season, while Matthews joined from the San Diego Chargers after an injury-hit campaign.

Reports have suggested that Murray will be RB1, but how coach Chip Kelly fits Matthews in is still unclear.

Murray told CSN: "I don't think it will be alternating series. But [Mathews] is a quality back, great guy, works extremely hard. I'm sure he'll get his fair share of touches. But I don't know how the rotation will be yet, we haven't touched on it."

The Eagles meet the Green Bay Packers this weekend in their third pre-season match.
