Yesterday it was reported that LSU senior defensive lineman Christian LaCouture and sophomore outside linebacker/end Isaiah Washington had both suffered what seemed to be significant knee injuries during Sunday’s practice, placing their status for the 2016 campaign in serious doubt.

As of Tuesday, the two have been ruled out for the season, according to a report from The Advocate. LaCouture tore the anterior cruciate ligament in his knee during a non-contact drill, and Washington sustained serious ligament damage as well.

While both injuries are setbacks for the Tigers’ defense, the loss of LaCourture can be considered a huge blow for the team.

“LaCouture’s highly anticipated senior season ended before it even began, and it throws the Tigers’ defensive line into unexpected shuffling mode a month before the season opener,” wrote The Advocate’s Ross Dellenger. “LaCouture, a 300-pounder who spurned the NFL to return for his senior year, was expected to play a key role in new defensive coordinator Dave Aranda’s 3-4 scheme.”

Last season as a junior, LaCourture recorded 35 tackles (2.5 for loss), a sack and a forced fumble in 11 games. Washington backed up Arden Key at the Buck position, seeing action in six games.
