LSU running back and leading rusher Clyde Edwards-Helaire missed practice Wednesday as he deals with a hamstring injury, coach Ed Orgeron told reporters.
Orgeron said it was a non-contact injury that Edwards-Helaire suffered Tuesday, but the extent of the injury isn't clear yet as the medical staff continues to perform tests.
"We're going to know more by the end of the week," Orgeron said.
The No. 1-ranked Tigers play No. 4 Oklahoma in the College Football Playoff semifinal game at the Chick-fil-A Peach Bowl on Dec. 28 in Atlanta.
The Sooners will be without suspended starting defensive end Ronnie Perkins, running back Rhamondre Stevenson and receiver Trejan Bridges, sources told ESPN.
