McNichols (ankle) is questionable to return to Monday's game against the Bills, Jim Wyatt of the Titans' official site reports.
Derrick Henry had both carries for the team on its first possession, and McNichols likely wasn't going to see many touches anyway. He only managed one limited practice during Week 6 prep due to an ankle issue, so he may have aggravated the injury during pregame warmups. Aside from Henry, Tennessee only has fullbacks Khari Blasingame and Tory Carter available out of the backfield.
