Harris (ribs) was listed as a non-participant in Wednesday's practice, Zack Cox of NESN.com reports.
Harris was in attendance for Wednesday's practice, but he apparently didn't take part in any team drills and thus wasn't designated as a limited or full participation. The running back's practice activity will be worth tracking closely the next two days to gain a better sense of whether he'll be ready to play Sunday against the Cowboys. If England's lead back is limited or out this weekend, Rhamondre Stevenson and Brandon Bolden would be next in line for work.
