The high-scoring 5-foot-10 Jones committed to the Cardinals in September and said he was "just so excited" to make it official.
"It feels so good to be a Louisville Cardinal," Jones told Cardinal Authority. "I don't want to say I felt like I was nervous or anything because I know I picked the perfect place.
"But it's just nice to get this off my shoulders. Now, I'm a Cardinal.",/p>
Jones, who originally signed with Tennessee and was a top 100 prospect out of high school in Memphis, Tenn., is considered the top junior college prospect in the country.
Jones is averaging 28 points a game at NW Florida. He said he plans on visiting U of L for a game, perhaps the matchup against Kentucky.
"I've been watching them and can't wait to see them play," Jones said. "I'm just excited."
