Cooper (wrist) was a limited participant at practice Thursday.
Cooper -- who has missed two straight games -- was also listed as a limited participant in Wednesday's walk-through session, so he'll probably need to practice fully Friday in order to approach Sunday's game against the Chiefs without an injury designation. For his part, Cooper told Alaina Getzenberg of ESPN.com on Thursday that he feels like he's trending toward playing Sunday. If Cooper is indeed able to face Kansas City, his availability would provide a major boost to a Buffalo pass-catching corps that will be without wideout Keon Coleman (wrist), and possibly tight end Dalton Kincaid (knee).
