The Facts: Mostert has been ruled out for Sunday's game against the Bills. He injured his thumb last Sunday and did not practice at all this week.

Diehards Line: Jeff Wilson Jr. and Salvon Ahmed will handle the backfield duties with Mostert out. ... LT Terron Armstead returned to practice in a limited capacity on Friday and he is listed as questionable to play this weekend. He is listed with knee, foot, hip, and pec injuries, but indicated this week that the leg injuries are the biggest hurdle to overcome. Quarterback Tua Tagovailoa (concussion) was ruled out earlier in the week. Guard Liam Eichenberg (hand) is listed as doubtful. Edge rusher Bradley Chubb (hand, ankle), quarterback Teddy Bridgewater (knee, finger), fullback Alec Ingold (thumb), tackle Kendall Lamm (ankle), and wide receiver Cedrick Wilson (hip, groin) are listed as questionable.
