Ankou (ankle) participated in Wednesday's practice, Sal Capaccio of WGR Sports Radio 550 Buffalo reports.

It's unclear how much Ankou did at practice, but it's encouraging to see him back in action after missing about a week with an ankle issue. The undrafted defensive tackle out of UCLA spent last season on the Bills' practice squad and is battling for a spot on the initial 53-man roster this year.
