Slay needed to clear waivers in order for him to make his way back to Philly, but the Bills ended up putting in a claim and adding him to their roster.
The Bills are looking for answers after dropping two surprising games lately, against the Dolphins and Texans. They’re currently second in the AFC East, behind the Patriots, but are still very much in the playoff picture at 8-4. They’ll add Slay as a veteran presence
UPDATE: NFL insider Ian Rapoport confirms the Eagles put a claim in on Slay. Philly is just one spot below the Bills in the claiming order. They have identical overall records at 8-4 but Buffalo has the tiebreaker in terms of an easier strength of schedule (.473 beating out .493).
