Stevenson (illness) has been placed on the reserve/COVID-19 list, Mike Reiss of ESPN.com reports.
Stevenson already had been ruled out for Sunday's game against the Bills, with Ian Rapoport of NFL Network noting that Stevenson's placement on the list was the result of a positive test. Stevenson thus will look to clear the league's COVID protocols ahead of Week 17 action, with both Damien Harris (hamstring) and Brandon Bolden (knee) -- who officially are listed as questionable -- poised to head New England's ground game this weekend, assuming they're active for the team's 1:00 p.m. ET kickoff.
