Nathan Cleverly will make his sixth world title defence at Cardiff's Motorpoint Arena on August 17, but the identity of his opponent remains up in the air.
Cleverly, the WBO light heavyweight champion, had agreed in principle to fight Sergey Kovalev, but the IBF today ordered title holder Bernard Hopkins to fight the Russian after he became mandatory challenger following his knockout win over Cornelius White last Friday.
Kovalev must now decide whether he wants to take on Cleverly in Wales, or Hopkins in the United States next.
