The Philadelphia Eagles seem to be in good shape at running back with starter LeSean McCoy, but who will back him up next season remains a mystery.

Veteran RB Jerome Harrison could become an unrestricted free agent depending what the rules are once a new CBA gets completed. McCoy saw time last season in roughly 76 percent of the offensive snaps.

And with the uncertainty behind McCoy, the Eagles have been evaluating running backs over the past few weeks.

RBs Kendall Hunter (Oklahoma St.), Alex Green (Hawaii) and DeMarco Murray (Oklahoma) have already visited the Eagles or are scheduled to do so before the draft, sources confirmed. The Eagles were also expected to work out RB Taiwan Jones (Eastern Washington), whose pro day workout is scheduled for Apr. 14, before the draft.

What gives Murray extra value to a team such as the Eagles is his ability to return kicks. He averaged 28.2 yards on 41 returns during his career at Oklahoma. He also was an effective receiver out of the backfield. Murray also visited the Dallas Cowboys this week.

RB Daniel Thomas (Kansas St.) also visited the Eagles this week.
