Dmitry Bivol avenged his loss to Artur Beterbiev with an inspired showing on Saturday, taking the undisputed light-heavyweight titles in a thriller in Riyadh.
In October, Beterbiev won a narrow, majority decision over Bivol in the same Saudi city, unifying all the belts and handing Bivol his first professional loss. On Saturday, Bivol flipped the script, winning a majority decision against his fellow part-Russian, who had never before been beaten.
