LSU coach Ed Orgeron said earlier Monday that linebacker Arden Key was questionable this week after suffering some minor injuries in the 33-10 win against Arkansas.
Key's absence at Monday's practice was expected but he was joined by two more defensive starters as linebacker Donnie Alexander and cornerback Greedy Williams were also not present during the portion of practice open to the media.
Alexander is coming off a game in which he had a career-high 12 tackles including five solo stops while Williams had a pass breakup and a late interception against Arkansas quarterback Cole Kelley.
It was Williams' fourth interception this season.
