Wisconsin transfer guard John Blackwell has canceled his scheduled visit to Louisville, per On3’s Joe Tipton. Blackwell visited Duke on Monday and, in turn, Tipton logged a prediction for the All-Big Ten transfer to ultimately join the Blue Devils.

The NCAA Transfer Portal officially opened on April 7 and closes on April 21. The new 15-day window was enacted following a recommendation by the men’s basketball oversight committee. Athletes don’t have to commit to a new school by the April 21 deadline.
