According to Mike Garafolo of Fox Sports 1, New Orleans Saints pass-rusher Hau'oli Kikaha tore his ACL in organized team activities, which likely means he'll end up on the injured-reserve list for his sophomore season in the NFL. Considering the personnel currently on the Saints' roster, Kikaha's loss can have a huge impact on the team's defense, which already led the NFL in points allowed and finished second in yardage allowed in 2015.
Kikaha wasn't a defensive end for New Orleans as a rookie, as he played an off-the-ball linebacker role, but he was a pass-rusher in college, both as a 4-3 defensive end and 3-4 outside linebacker.
