Bourne still has a chance to play in Sunday's game against the Bills after being placed on the reserve/COVID-19 list this Wednesday, Mike Reiss of ESPN.com reports.
Bourne is vaccinated, and the timing of his placement on the COVID list gives him several days to test negative on back-to-back days. It's still probably no better than 50/50, and the Pats also have other issues at wide receiver with Nelson Agholor (head) and N'Keal Harry (head) both getting banged up during Saturday's loss to Indianapolis.
