King and Deng Adel had 10 apiece for Louisville (18-10, 8-7), playing for the first time since an NCAA panel upheld sanctions against the program in the wake of its sex scandal — which cost the school about $600,000 in tournament revenue, 123 victories and its most recent national championship.

at No. 12 Auburn 90, Alabama 71: Jared Harper scored 21 points, Chuma Okeke had 16 points and 10 rebounds, and Auburn beat rival Alabama even without ailing star Mustapha Heron.
