Cooper (wrist) remained a limited participant at practice Thursday.
Cooper, who was inactive for this past Sunday's win over the Dolphins, also was limited in Wednesday's walkthrough, so he'll presumably need to practice fully Friday in order to approach this weekend's game against the Colts without an injury designation. In addition to Cooper, three other Bills receivers -- Keon Coleman (wrist), Mack Hollins (shoulder) and Curtis Samuel (pectoral) -- are nursing injuries as Sunday's game nears.
