DeMarco Murray hasn't received a call from the Dallas Cowboys since last week as he begins his free agency.

Murray deleted all references to the Cowboys in his Twitter bio.

Although Murray will be one of the most coveted running backs on the open market, a league source told ESPN last week that the two-time Pro Bowler likely would return to the Cowboys if their offer was financially similar to those he receives from other teams.

That report, however, was published prior to this extended period of silence between Murray and the Cowboys.

Murray led the NFL in rushing with 1,845 yards on 392 carries in 2014.
