12:51pm: The Bills have officially signed Wynn, the team announced today in a press release.
11:46am: The Bills further fortified their defensive line today, agreeing to terms on a contract with free agent defensive end Jarius Wynn, according to Mark Gaughan of the Buffalo News. Gaughan tweeted earlier today that the club was hosting Wynn on a free agent visit.
Wynn, 27, started his career with three seasons in Green Bay before spending the last two seasons with the Titans, Chargers, and Cowboys. The former sixth-round pick has never been more than a part-time player, though he has recorded at least two sacks in each of his last three seasons. In his five-year career, he has yet to receive a positive grade from Pro Football Focus, having earned a score of -11.0 in just 369 defensive snaps in 2013 (subscription required).
