ANTHONY JOSHUA vowed to fight on despite being crushed inside five rounds by IBF world heavyweight champion Daniel Dubois at Wembley on Saturday night.

Joshua was floored four times as the magnificent Dubois launched a relentless assault from the first bell that eventually ended with the clear favourite being counted out following a thrilling exchange of blows.

It was a devastating defeat and the fourth of his career which robs him of a shot at becoming undisputed world champion.
