Lyle originally chose the Cardinals in June over offers from Tennessee, Florida, Indiana, Illinois and Ohio State, among others.
"I just felt like I needed to make sure I made the right decision for me," he told the paper. "I didn't really think Louisville was the best decision for me."
Lyle is the second point guard to renege on his commitment to the Cardinals in the last two months. ESPN 100 prospect and Louisville native Quentin Snider (Ballard High School) opened up his recruitment in July before committing to Illinois earlier this week.
