Harris (hamstring) was listed as a limited practice participant Wednesday.
The fact that Harris has been able to work in a limited fashion on consecutive days coming off New England's Week 14 bye suggests that he has a chance to suit up Saturday against the Colts, though there's a solid chance he'll approach the contest with a questionable designation. If he's cleared ahead of the 8:20 p.m. ET kickoff, Harris may still face competition for carries from Rhamondre Stevenson, who has taken on an enhanced profile in the New England rushing attack in recent weeks.
