Bills to cut injured IK Enemkpali, sign linebacker Biermann

PITTSFORD, N.Y. (AP) The Buffalo Bills will release defensive end IK Enemkpali after he sustained a season-ending injury to his right knee.

The Bills placed Enemkpali on their waived/injured list on Monday, shortly after coach Rex Ryan said the player has a torn a ligament in his right knee.

The move freed up a roster space for Buffalo to sign linebacker Kroy Biermann and address its injury-depleted pass-rushing depth.

Biermann is a free agent, who spent his first eight seasons with Atlanta.

Enemkpali was hurt late in the second quarter of Buffalo's 19-18 preseason-opening loss Indianapolis on Saturday.

Enemkpali was playing in place of projected rookie starter Shaq Lawson, who will miss at least the first month of the season because of shoulder surgery. Lawson's primary backup, Manny Lawson, is expected to miss a few more weeks recovering from a partially torn pectoral muscle.

The Bills claimed Enemkpali off waivers a year ago after he was released by the New York Jets for punching and breaking the jaw of quarterback Geno Smith during a locker-room confrontation.
