Browne was always looking for a one-punch haymaker finish but just couldn’t get close enough to a trim and lively Whyte, who opened up a bad cut in the very first session.
The eye damage worsened every round before a busted nose added to Browne’s troubles in the fifth.
In the sixth, Whyte turned Browne’s lights out completely with a sickening blow.
‘Big Daddy’ was worryingly down for some time and didn’t move, but with the help of the ringside medics, was soon back to his feet to the relief of Whyte and the UK crowd.
A trip to be medically assessed ended with good news for Browne’s supporters.
“Hi everyone. Thanks very much for the love and support. It wasn’t my night and massive respect to Dillian Whyte for his performance,” said Browne.
“My eye was giving me trouble from the second and you can’t protect from what you can’t see. I’m all good and I will be back.”

Whyte could now move on to a rematch with Anthony Joshua should his old rival come through Joseph Parker in Cardiff next week, whilst Browne has a rebuilding job to do for the first time in his boxing career.
After the contest, Whyte called out Deontay Wilder to agree a WBC title fight, although the Londoner could be ordered to face Dominic Breazeale in a final eliminator first.
Wilder, on the other hand, has his focused fixed on ex-Whyte opponent Anthony Joshua.
