LSU linebacker Arden Key (49) and LSU defensive tackle Rashard Lawrence (90) celebrate a defensive play during the first half of the LSU-Louisville Buffalo Wild Wings Citrus Bowl football game Saturday Dec. 31, 2016, in Orlando, Fla.

Defensive end Rashard Lawrence returned to LSU practice Monday, while nose tackle Ed Alexander sported a cast on his right hand and forearm.

Lawrence’s participation in practice points to his potential return this week. Ed Orgeron said earlier Monday that coaches were hopeful Lawrence would play in LSU’s game Saturday against Syracuse. He missed the last two games with an ankle injury he suffered in the season opener against BYU.

Alexander will not play this week, Orgeron said earlier Monday. The 330-pound sophomore only watched practice, his right arm in a sling with a cast running from his hand to near his elbow. Alexander appeared to re-injure the right hand in the first half of last week’s 37-7 loss at Mississippi State. Alexander played with a fractured bone in his right hand for much of last season, wearing a club-type apparatus on the hand.

Other practice observations:

  • Starting nickelback Kary Vincent, who left Saturday’s game with what looked like a left arm injury, participated in Monday’s drills. Xavier Lewis replaced Vincent in the second half of Saturday’s loss.
  • Quarterback Lowell Narcisse, for a second straight week, was practicing as the scout team quarterback. Narcisse did not make the travel squad to Starkville. Signs point to a potential redshirt coming for the freshman dual-threat player.
  • Defensive end Frank Herron was at practice, but is not expected to play this week. He donned a scout team jersey Monday. 
  • Receiver Dee Anderson practiced Monday, just the second time all fall that reporters have spotted him during drills.
