Phidarian Mathis is back from his suspension, who will the Bills let go to make room on the roster?

Veteran defensive lineman Phidarian Mathis was added to the active roster yesterday after serving a three-game suspension to start the season.

Upon doing so, it started a 48-hour clock to make a corresponding move to stay within the NFL's roster limits.

In June, I wrote a piece on Mathis highlighting what I believed would be an emergent season for the veteran because of the more two-gapping nature of Jim Leonhard 's defense — compared to Sean McDermott's — and Mathis' brilliance controlling two gaps at Alabama under Nick Saban.
