News: Polk (hamstring) is listed as probable for Sunday's game against the Cardinals after participating fully in practice all week.
Impact: 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.
News: Kendricks is listed as questionable for Sunday's game against Arizona.
Impact: Kendricks participated fully in Friday's practice, an encouraging sign as he makes his case to play for the first time since Week 2. If he plays, he will likely slide into the lineup at inside linebacker next to DeMeco Ryans (groin).
News: Sproles (knee) is listed as questionable for Sunday's game against Arizona.
Impact: First, the good news: After two days of limited practice, Sproles was a full participant Friday and seems like he has a very real chance of returning from his torn MCL earlier than expected. The bad news: the matchup against the Cardinals is brutal. Arizona's top-ranked run defense has not allowed any opposing runner to surpass 64 rushing yards in a game this season. Of course, Sproles' value lies more in his utility in the pass game.
