IK Enemkpali didn't finish the Buffalo Bills' preseason Week 1 tilt against the Colts after suffering a knee injury, and he now he's out for the rest of the season as well.
An MRI confirmed that Enemkpali suffered a torn ACL and will miss the entire season, a source told NFL Media Insider Ian Rapoport.
The linebacker was carted off the field in the first half of the game. He reportedly twisted his right leg awkwardly while trying to pass rush. Bills coach Rex Ryan described the injury as "major" during halftime of the game broadcast.
