Who won the boxing last night? Haney vs. Lomachenko, Taylor vs ...

There were two undisputed title fights last night, and both delivered on entertainment.

Live on DAZN, undisputed light welterweight champion Chantelle Cameron held off a fierce challenge against Katie Taylor, and there is already talk of an autumn rematch, perhaps at lightweight.

There were also disappointing defeats for both Sam O'Maison and Gary Cully in their undercard fights.

In Las Vegas, there was a controversial outcome as Devin Haney was awarded a unanimous decision victory over Vasiliy Lomachenko, as the unbeaten American retain his undisputed status at lightweight.

Earlier in the night, Junto Nakatani defeated Andrew Moloney to win the vacant WBO junior bantamweight strap.
