Ultimate Boxxer returns to the Indigo at The O2 on Friday 20th September, giving eight boxers a shot at glory live on BoxNation.

The fifth instalment of the exciting tournament sees eight Super-Welterweights go to battle to win the Golden Robe.

Ahead of UB V next week, here we revisit some of the highlights from the four previous tournaments:

Knockdowns and Knockouts (UB II)

The second tournament at Light-Heavyweight was also held in the capital, with Birminghan's Shakan Pitters coming out on top.

Pitters earned a unanimous decision over Dec Spelmen in the final, but there were plenty of knockdowns and a few stoppages along the way, which makes the format so appealing.

Punching Preacher (UB III)

Derrick Osaze has an unusual background as an ordained minister and boxer, but watching him in action in the third instalment of Ultimate Boxxer you wouldn't think he's committed to a life of non-violence.

Chambers v Earlington (UB IV)

Back in July the Ultimate Boxxer crowd witnessed the best fight in the tournament's history as Damian Chambers went to war with Rhasian Earlington in Altrincham, Greater Manchester.

Cruiserweight Carnage (UB IV)

As a whole, Ultimate Boxxer IV was probably the best tournament since the concept started. It was the turn of the 200lb class two months ago and they didn't let us down.

The Super-Welterweights have a lot to live up to next week.

Mikael 'Lethal' Lawal (UB IV)

After Chambers edged past Earlington in the semis, the final man standing in his way was Nigeria's Mikael Lawal.

'Lethal' won the Cruiserweight tournament in dramatic fashion, knocking Chambers out in just 94 seconds with a brilliant left hook.
