The Bills hosted Davis for a tryout Wednesday, Field Yates of ESPN reports.
Davis retired last August while he was with the Jets, but he applied for reinstatement to the NFL back in March, and he's now attempting to latch on with a new AFC East team. Buffalo could be looking to replace the big-bodied Chase Claypool (toe) at training camp, as he landed on season-ending injured reserve Tuesday. If Davis signs with the Bills, he could push fellow veterans Mack Hollins, Marquez Valdes-Scantling and KJ Hamler for a depth role in the receiver room.
