Dmitry Bivol's ex-wife Ekaterina congratulates her ex-husband's opponent Artur Beterbiev after he became the undisputed champion.

Artur Beterbiev beat Dmitry Bivol for the unified light heavyweight title Saturday in Saudi Arabia. Round-by-round analysis for main event, undercard.

Bivol was class in defeat, as expected, and praised Beterbiev; they had shared a unique respect for each other during the months and months it took to finally get the pair in the ring. They had also shared six years and nine months as world champions before the final bell separated Bivol from his belt.
