The junior announced on Twitter Sunday night that he has a torn anterior cruciate ligament and will miss the remainder of the season.
Laulu-Pututau suffered the injury during BYU’s first series in its eventual 35-7 loss to Washington on Saturday in Seattle.
“I have torn my ACL and will be needing surgery,” the player known as MLP wrote in a tweet Sunday. “It hurst so much more emotionally and mentally than it does physically but I won’t be returning [until] the 2019 season.
Laulu-Pututau sustained a Lisfranc foot injury in practice a few days before the 2017 season opener.
