Anthony Joshua and Joseph Parker put their undefeated records on the line and the WBA, WBO, IBF and IBO heavyweight belts into one pot and faced off at the Principality Stadium in Cardiff for heavyweight supremacy.

In the first round, both fighters looked to establish their jab but it was Joshua who took the center of the ring and backed Parker up, both fighters landed very little but it was Joshua who looked in charge.

In the second round again it was Joshua who took charge, starting to find his range and keeping Parker moving on the back foot, having to work hard to keep Joshua off him.

Through rounds three and four, it was Joshua again taking charge keeping Parker on the move, neither fighter landing much but the odd blow, however, Joshua was possibly 4-0 rounds up at this point.

A more positive 5th round saw Parker begin to let his hands go more, taking risks and getting inside, a much better round from the New Zealand fighter

In the 6th round, the fight exploded into life as both fighters engaged each other landing solid punches, Parker growing in confidence, it looks like we may finally have a fight on our hands.

In the 7th and this fight has become a very competitive fight, neither fighter able to dominate the other, both trying to set traps. In the 8th both fighters were feeling the pace, in the last minute, Joshua exploded into life landing a three punch combination, however just as the fighters began to engage the referee stepped in to split them up, unnecessary, and not for the first time in the fight.

Into the 9th, and the rounds were becoming subjective, Joshua taking center of the ring, looking the dominant fighter, however, Parker having moments, in spurts. Parker clearly a few rounds down from the early rounds needs a late rally in the championship rounds.

Into the 10th and championship rounds and Joshua dominating it, putting real pressure on Parker who looks like he needs a knockout in the final two rounds to retain his world champion status.

Into the 11th and another Joshua round, the Olympic gold medallist just needs to stay on his feet in the final round to surely unify the WBO, WBA, IBF and IBO heavyweight titles.

The 12th and final round did little to change the course of the fight,  Anthony Joshua has surely unified by wide margins on the judges scorecards, it has to be said the referee did little to help the flow of the fight, constantly breaking up the fighters unnecessarily.

The scorecards were in, 118-110 x 2, 119-110, Anthony Joshua was unified heavyweight champion by unanimous decision.
