Former Chargers receiver Jeremy Butler is signing a one-year deal today with the Bills, a source tells Adam Schefter of ESPN.com (on Twitter). Financial terms of the deal are not yet known. 
Butler was non-tendered by Los Angeles last week. Butler appeared in four games last season for the Bolts and caught only two passes for eleven yards. In between his time with the Ravens and Chargers, he had a brief stint with the Jets.
The 25-year-old (26 in April) appeared in eight games in 2015, collecting 31 catches for 363 yards. Extrapolated to a full season, those are some pretty solid numbers. That’s likely the kind of playing time and production he’s shooting for in 2017 with Buffalo. The Bills now have a quality receiver to help support star Sammy Watkins. The rest of the WR depth chart isn’t exactly star studded. Philly Brown (newly signed), Dezmin Lewis, Walt Powell, and Kolby Listenbee are the team’s other receivers under contract.
Butler’s departure still leaves the Chargers with Keenan Allen, Tyrell Williams, and Travis Benjamin as their three best wide receivers. Butler would have slotted no higher than the team’s WR4 had he re-signed.
