No. 1 LSU and No. 4 Oklahoma could be missing key players in the Peach Bowl playoff semifinal. LSU’s top rusher, Clyde Edwards-Helaire, missed Monday’s practice after suffering a hamstring injury last week in practice. The Tigers may have to rely on three backups, including freshmen Tyrion Davis-Price and John Emery. Edwards-Helaire ran for 1,290 yards with 16 touchdowns as a first-team All-SEC back. Meanwhile, Oklahoma coach Lincoln Riley has confirmed that three players will be suspended for the game. Sacks leader Ronnie Perkins is among those suspended.
