The Bills have signed defensive end Ryan Davis, according to a team announcement. Terms of the deal are not yet known. 
Davis played in 30 games for the Jaguars in 2014-15 and racked up ten sacks between the two seasons. After that, the Jaguars placed a second-round tender ($2.55MM) on him to prevent him from leaving in free agency. Then, Jacksonville surprised everyone by dropping him in September of last year. After that, he hooked on with the Cowboys and was used largely as a special teamer. Unfortunately, he suffered a knee injury late in the regular season which prevented him from suiting up in the playoffs.
It’s not immediately clear what kind of role Davis is ticketed for in Buffalo. He may get a chance to return to a traditional workload on defensive end with Corbin Bryant and Leger Douzable still out there as free agents. If neither player is retained, there should be more playing time available for Davis behind projected starters Adolphus Washington and Kyle Williams.
Last year, Davis joined Dallas on a modest one-year, $675K deal.
