Chris Polk understands the situation.
Matthew Tucker is also back and could challenge for snaps.
Polk is simply going to compete as hard as possible to make his case for playing time.
"We've got a great stable of backs so realistically it's gonna be LeSean taking most of the carries," Polk told Phillymag.com. "So whatever I can do to get on the field and help the team win, I'm gonna do it -- whether it's blocking, catching, special teams. ... The more you can do, the better off you are making the team."
Polk played a total of 46 offensive snaps last season and maximized his time. He had four carries for 50 yards and a touchdown in a blizzard against the Detroit Lions. Polk wound up with 11 carries for 98 yards all season.
Polk suffered a right shoulder injury against the Tampa Bay Buccaneers in October and eventually had surgery.
"I just feel more free," Polk told Phillymag.com. "Now I don't have to wear both shoulder harnesses so I'll be able to move my arms better, be able to move a little faster, do a little more."
Polk is unsure what will occur this season, but he will continue to prove himself on a daily basis to the coaching staff.
"Me not getting drafted, me being here in a great organization, they made me really feel like I was at home," Polk said. "Them showing that they believe in me, to keep me here after these years … it's up to me to hold up my end of the bargain now. That's what I intend to do."
