LSU cruised to a 38-0 win over New Mexico at home on Saturday, but it did so without one of its key defensive players, safety Major Burns, who was sidelined by a neck injury.
Tigers coach Brian Kelly told reporters after the game that Burns will miss the next 3-6 weeks recovering from the injury.
"I don't want to get into specifics when you're talking about a neck injury, but he's been cleared by all the doctors," Kelly said. "He needs some rest."
Burns entered the weekend second on the team with 17 tackles.
