LSU RB Leonard Fournette sprains ankle in practice

LSU running back Leonard Fournette sprained his ankle during Tuesday's scrimmage and has been placed in a walking boot.

The Heisman Trophy candidate sustained the injury at the end of the play in which a tackler landed on his leg.

Tigers coach Les Miles termed the injury as minor and emphasized it wasn't a high ankle sprain.

"Leonard Fournette got a slight sprain," Miles said. "He's in a boot. Some of the healing (is) going. It's not terrible."

Miles didn't have a timetable for when Fournette might return to action.

Fournette rushed for 1,034 yards and 10 touchdowns as a freshman in 2014 and had 1,953 yards and 22 scores last season.

Fournette finished sixth in last December's Heisman Trophy balloting.
