Per ESPN's Adam Caplan, the Buffalo Bills are hosting free agent defensive end Leger Douzable today.
Douzable, 30, was an undrafted free agent pickup by the St. Louis Rams in 2009 and has spent time with four teams, including the last three seasons with the New York Jets. That, of course, means he spent two seasons playing in Rex Ryan's defense in New York. He's appeared in every game over the last three seasons, although he didn't earn a start until last season, after Rex had left town.
Douzable seems to have all the hallmarks of a reliable rotational player.
