The reason for Polk's absence was not provided, as the Eagles were not required to submit an official injury report Tuesday. Expect an update on his status if it turns out he is dealing with a health issue.

Polk had eight carries for 50 yards and a touchdown Sunday against the Texans.

Polk didn't get a single touch until 3:17 left in the third quarter, but he made his touches count, rushing for 22 yards and then scoring on an eight-yard run on back-to-back plays. He did the rest of his work in the fourth quarter with the Eagles comfortably ahead, but it looks like he's starting to play more of a backup role ahead of Darren Sproles (three carries for 17 yards), who continues to do more damage in the passing game (four catches for 46 yards). Unfortunately, Polk's fantasy value is still fairly limited given LeSean McCoy and Sproles are still ahead of him on the depth chart.

Polk is in line for his first touch of the season due to Darren Sproles' (knee) absence. Still, the existence of LeSean McCoy in the Eagles' backfield doesn't provide much confidence that Polk will receive more than a handful of looks.

It's looking increasingly likely that Sproles will miss the game; ESPN's Chris Mortensen reported that he does not expect him to play. Polk would be the biggest beneficiary of a Sproles absence, but the third-year runner has yet to receive a carry this season and would probably be limited to a bit role on offense behind LeSean McCoy.

Buried on the running back depth chart, Polk's primary value to the Eagles right now is on special teams as a return man. He should be available Sunday if you need him in a return-yardage league.

Polk missed the vast majority of training camp due to a Grade 2 tear of his hamstring, meaning the injury suffered Sunday is cause for concern. His lack of a touch on offense this season doesn't lend itself to much fantasy utility, but if he sits out in Week 6, the Eagles' will require a replacement on kickoff returns. An absence would result in Josh Huff or Nolan Carroll taking on such duties.

Polk suffered a hamstring injury during Sunday's win over the Rams, the Philadelphia Inquirer reports.

Polk missed the entire preseason due to a hamstring injury, so Sunday's latest occurrence is somewhat concerning. While Polk hasn't been handed a single carry this season, he has been the Eagles' kickoff returner to date, totaling 202 yards and one touchdown on five run-backs through five games. Should he be sidelined moving forward, Darren Sproles could add kickoff return duties to his current punt returner role.
