The Miami Dolphins could be without both starting receivers Sunday against Buffalo.
Brian Hartline and Davone Bess, who have combined for nearly half of Miami's receptions, missed practice Thursday with back injuries. Bess sat out Sunday's win over Jacksonville, and Hartline was hurt in that game.
If neither plays, quarterback Ryan Tannehill's options at wide receiver will be Marlon Moore, rookie Rishard Matthews, newcomer Armon Binns and converted running back Marcus Thigpen. The foursome has combined for 13 catches with the Dolphins this year.
