A person familiar with the decision says No. 1 LSU has suspended star cornerback Tyrann Mathieu, along with
defensive back Therold Simon and running back Spencer Ware for this Saturday's home game against Auburn.
The person told The Associated Press about the suspensions on condition of anonymity on Wednesday because they have not been announced.
LSU spokesman Michael Bonnette declined to confirm any punishment for the three players, saying only that they're involved in an internal matter that coach Les Miles "will handle accordingly."
Mathieu has forced four fumbles, recovering three and returning two for scores.
He also has two interceptions and 42 tackles including 1½ sacks.
Ware is the leading rusher for the unbeaten Tigers with 512 yards and six touchdowns.
Simon has one interception and 29 tackles.
