Stevenson (illness) has been ruled out for Sunday's game against the Bills, Mike Reiss of ESPN.com reports.
Stevenson won't be available this weekend after missing practice this past week, and in his absence expect Damien Harris (hamstring) to head the Patriots' Week 16 rushing attack, with Brandon Bolden (knee) serving as the team's primary change-of-pace back. That said, both Harris and Bolden officially are listed as questionable by the team, so it's advisable to confirm their statuses prior to New England's 1:00 p.m. ET kickoff Sunday.
