Sal Capaccio of WGR 550 reports that Ankou is in Buffalo for the second time this offseason. The Bills have three open roster spots, so a deal could happen at any time.
Ankou signed with the Falcons shortly after his first conversation with the Bills, but his stay with the team came to a end last weeks. The Falcons cut Ankou while bringing in a handful of other defensive linemen.
Ankou had five tackles in seven games for the Cowboys last year and has 31 tackles and 1.5 sacks in 27 career NFL games.
