Polk still hampered by hamstring injury

Watching from the sidelines is never easy.

It's especially tough when you're trying to prove yourself to the coaching staff.

For Philadelphia Eagles running back Chris Polk, Thursday's preseason finale against the New York Jets looms large.

Yet there's a Catch-22 with Polk.

A hamstring injury has hampered him throughout training camp and the preseason.

This final preseason game is the perfect opportunity to shine. Beyond LeSean McCoy and Darren Sproles, there has been healthy competition between Polk, Matthew Tucker, Henry Josey and Kenjon Barner.

"It's tough especially when things start to work in your favor," Polk told Philadelphiaeagles.com. "You're sitting out and it's hard just sitting there and watching other people play and play well because you want to go out there and show what you can do. It's a process. Everything happens for a reason."

Polk wants to play against the Jets. But he also wants to be smart.

"It's definitely going to be like a preview because I've been out for a month. It's my first week practicing," Polk told Phildelphiaeagles.com. "I treat every day like it's my last day. You never know what's going to happen. It's always on the line. I wasn't promised anything. I'm not guaranteed anything being that we have a great host of backs. I'm renting space here. You just have to do the best that you can and work as hard as you can while you're here."

In limited playing time last season, Polk scored three touchdowns on just 11 carries.

He desperately wants to be part of the final roster once again. Final cuts will come Saturday.

"It's more what you're doing now. I feel like that would be a little bit of consideration, but it really comes down to what happens, how the game goes and who's playing, who isn't playing," Polk told Philadelphiaeagles.com. "It's going to be a real tough decision because we have a lot of great guys that deserve to make the team, that deserve to be on the team. Not everyone can win."
