BASKETBALL Reports: Arthur Kaluma withdraws from NBA draft
Kentucky, Alabama and Texas are some of the teams said to be interested in Kaluma.
Shooting 11-for-18 from the field, Diarra was too big for Petro and limited Ater Majok and Jone Pedro in the paint.
The bronze game will see the two sides that finished top of their respective conferences in the regular season facing off for what is left in the campaign for them.
Al Ahly will carry the favourites' tag going into the final, but basketball games are won on court and not in the record books.
The pair of Jean Jacques Boissy and Marcus Crawford was unplayable for Petro and made it tough for every matchup thrown at them.
He shot nine-for-13 from the field, including a near-perfect rhythm of four-for-five from downtown.
