Edge rusher Arden Key was missing from LSU's practice Tuesday while recovering from a right knee injury that forced him to miss the game at Tennessee.

Key participated in LSU's walk-through practice Monday but did not appear full strength. At one point Monday, he stepped away from drills to speak with LSU medical personnel and adjust the brace on his right knee. 

Key, a junior All-American, remains "questionable" for Saturday's regular season finale against Texas A&M on Saturday night, but his absence from Tuesday's practice does not bode well for his return. He suffered the knee injury late in the first quarter of the win over Arkansas. He returned and played the next two quarters of that game. 

Other observations from practice

  • Inside linebacker Donnie Alexander, who like Key did not travel to Tennessee because of injury practiced for a second straight day. He wore a gold jersey, signifying limited contact because of injury. He went through drills alongside starter Devin White. Alexander inured his shoulder or neck against Arkansas. 
  • LT KJ Malone participated in practice for a second straight day, but did not run through drills with the starting group. He does not appear to be full strength, walking gingerly on an injured knee. 
  • Also in gold Tuesday: F-back Tory Carter, OLB Corey Thompson, edge rusher K'Lavon Chaisson and CB Kevin Toliver.
