The Bills announced wide receiver Cole Beasley (knee) and tight end Reggie Gilliam (knee/hamstring) will be out for Sunday's game against the Dolphins.
The two did not practice this week and are both week-to-week per Bills head coach Sean McDermott. Beasley injured his knee at the end of the Week 16 game agains the Patriots.
Bills quarterback Josh Allen said Beasley will do whatever he can to get healthy.
"I know Cole is going to do everything in his power to be out there," Allen said earlier this week. "If it's not this week, then it'll be next week. He's chomping at the bit already. He's going to attack the next week and a half or the next week hard and do whatever he can to get back on the field."
