LSU's defense suffered a blow on Tuesday when news emerged that linebacker K'Lavon Chaisson will be out for the season with an injury.
Chaisson, a sophomore from Houston who was the No. 34 overall recruit in the 2017 ESPN 300, suffered an apparent knee injury in the fourth quarter of the Tigers' 33-17 win over Miami on Sunday.
Coming into the season, the 6-foot-4, 238-pound Chaisson was slated to succeed Arden Key as the Tigers' edge rusher in their 3-4 alignment. He played in 12 games as a true freshman in 2017, starting three and earning a spot on the 2017 SEC All-Freshman team.
