Maclin inked a practice-squad contract with Buffalo on Monday, Alec White and Mike Maynard of the team's official site report.
Maclin joined the Bills as an undrafted free agent in early May and had some promising moments during the preseason slate, including a 71-yard touchdown catch. He was waived Sunday but will remain in the Buffalo organization on the practice squad. Maclin's path to game-day opportunities will likely depend upon the health of the Bills' receiver corps.
