LSU running back Leonard Fournette (7) on the sidelines against Missouri in the second half, Saturday, October 1, 2016 at LSU's Tiger Stadium in Baton Rouge, La. LSU won 42-7.

LSU running back Leonard Fournette is expected back for the Tigers' next game Saturday at No. 18 Florida, coach Ed Orgeron told ESPN.com on Sunday.

The Tigers (3-2, 2-1 Southeastern) beat Missouri 42-7 on Saturday night in Orgeron's debut, rolling up the most offensive yards (634) in a league game in school history despite missing their star tailback.

Fournette did not dress out while nursing a lingering left ankle injury. He sprained his left ankle during preseason camp, re-injured it in the Sept. 3 season opener against Wisconsin and appeared to injure it again last week at Auburn on LSU's final drive. Fournette did not practice this past week, Orgeron said.

Asked after the game if Fournette could have played if LSU "needed him," Orgeron said, "No, he wasn't ready."

LSU meets the Gators (4-1, 2-1) at 11 a.m. on Saturday in Ben Hill Griffin Stadium.

Fournette missed the Sept. 10 game against Jacksonville State after re-injuring the left ankle in the season opener. LSU ran for 418 yards without Fournette, the most in a game since 1996. It got 163 yards from Derrius Guice and 131 from Darrel Williams. The Tigers averaged 8 yards a carry.
