Blue will likely share playing time if Arian Foster (groin) is available for Sunday's game against the Bengals, the Houston Chronicle reports. Foster was a limited participant in Wednesday's practice after missing last week's game. It's important to note that the Chronicle is speculating about Blue's role in the event Foster returns this week against the Bengals; it does not indicate head coach Bill O'Brien making any inferences about either player's intended role. O'Brien will only go as far as saying that Foster is "day-to-day" and that he has "a lot of confidence in" Blue. The one other time this season when Foster returned from an injury was Week 4 against Buffalo. In that game Foster carried the ball eight times and Blue had nine carries. Though it's important to note that Foster had two weeks of preparation for the Bills and this time he's had three weeks to heal up for the Bengals.
