After serving his four-game league-imposed suspension the Bills added DE IK Enemkpali to their 53-man roster Monday. Enemkpali had been an exemption on Buffalo's roster the last four weeks.
The defensive end was originally signed by Buffalo after his release by the Jets this past August. Enemkpali had been involved in a locker room altercation with Jets QB Geno Smith in which Smith sustained a broken jaw.
In four preseason game appearances for Buffalo, Enemkpali posted 11 tackles. He's expected to serve as a rotational end to help keep starters Mario Williams and Jerry Hughes fresh and play a role on special teams.
To make room on the roster for Enemkpali the Bills placed RB Cierre Wood on injured reserve. Wood sustained a knee injury in Sunday's win at Tennessee and had to be carted to the locker room.
