Oregon freshman running back Thomas Tyner is dealing with a left leg injury, the Oregonian reported.
Tyner left practice Tuesday with his leg in a walking boot and needed crutches to move around. Per school policy, Oregon would not comment on the exact nature of the injury.
Tyner set a new Oregon single-season rushing record by totaling 3,415 yards as a senior for Beaverton (Ore.) Aloha. Tyler also ran for 10 touchdowns in a single game and holds the state record in the 100-meter dash.
