Arden Key

The playing status of All-American edge rusher Arden Key remains in serious doubt after he missed a second straight practice on Wednesday. 

Key, LSU's standout junior, is recovering from a right knee injury he suffered against Arkansas two weeks ago. He missed the Tigers' game at Tennessee and could miss the regular season finale against Texas A&M on Saturday — likely the final home game of his career. 

Key, a projected NFL first round pick who coaches expect to go pro, attempted to practice during LSU's walk-through, indoor drills Monday. He participated in some drills but stepped away to speak with medical personnel and adjust a new brace he wore on the right knee. 

Key injured the knee late in the first quarter of the win over the Razorbacks. He played the next two quarters before exiting the game with LSU up big and 10 minutes left. 

Key's replacement, freshman K'Lavon Chaisson, donned a gold jersey at practice for a second straight day. Gold jerseys signify limited contact because of injury. He fully participated in individual drills during the 5-minute of observation time reporters were allowed.

Other practice observations

  • LT KJ Malone participated in more action Wednesday than he did Tuesday as he works to overcome a lingering injury to his knee. Malone plans to dress out for his last home game, despite still experiencing pain in the knee. 

  • OLB Corey Thompson shed the gold jersey he wore during Tuesday's practice, a potential sign of an improving and undisclosed health issue. Several other players remained in gold, including ILB Donnie Alexander, F-back Tory Carter and CB Kevin Toliver.
