Cooper (wrist) was listed as a limited practice participant Wednesday.
According to Maddy Glab of the Bills' official site, head coach Sean McDermott suggested that Cooper would be a non-participant in the team's first Week 9 session, but the wideout ended up getting some work in after all. Alaina Getzenberg of ESPN.com noted that Cooper participated in the Bills' wideout drills, and then a bit more in the drills that followed during the portion of Wednesday's practice that was open to the media. Cooper now has two more chances to increase his practice participation ahead of Sunday's game against the Dolphins.
