It appears that Chris Polk has supplanted Bryce Brown as the No. 2 running back for the Eagles. Brown did not record a carry.
Polk did not record a carry and dropped a third-down pass, which was the only pass intended for him. He also played on special teams. Polk rushed for a touchdown last week and earned the praise of the coaches, who said he deserves more playing time.
Something to keep in mind if you're a McCoy owner. If McCoy would go down it's likely there would be some sort of split anyway, but at this point it looks like Polk would be in line for a majority of the work and perhaps even goal line chances, given he's the bigger back.
