The Buffalo Bills, currently holding a 2-0 record, must soon open a roster spot for Phidarian Mathis following the conclusion of his suspension after Week 4. This move puts veteran defensive lineman Greg Gaines, who joined the team in August 2026, in a position where he may be waived.
Why it matters
The Bills are navigating depth challenges and must clear a place for Mathis to return to the active roster. This adjustment will likely impact the team's defensive rotation, where Gaines has functioned in a limited capacity during the early season.
Greg Gaines, entering his 8th NFL season, played 14 snaps in the season opener and 19 snaps during the second game. The team currently holds a 2-0 record as they prepare to host the Los Angeles Chargers.
