And the 5-foot-10, 210-pound Vaughn said he liked what he saw.
Vaughn, who has already visited Purdue, is expected to visit Ohio State on Dec. 13. He has also said Tennessee, Vanderbilt and Wisconsin have also been in the mix.
"I like how Louisville uses the running back in their offense," Vaughn said. "They told me I could come in and compete for playing time, I liked them and the game was live.
"They're one of the schools at the top for me."
Vaughn said he doesn't have a timetable for making a decision, but noted he didn't want to stretch it out too long before making a final decision.
"Sometime in late December for sure," he said.
Vaughn is ranked as the No. 56 running back in the class by Scout.com. He was also at U of L for the season-opening win over Miami.
As a senior, Vaughn averaged 12.5 yards a carry and finished with over 2,200 yards and 40 rushing touchdowns. Vaughn was named Class 2-A Running Back Mr. Football in Tennessee.
