Anthony Joshua takes on Joseph Parker at Cardiff's Principality stadium in a much-anticipated heavyweight unification fight on March 31.
After Joshua's last fight where he was made to work for his knockout victory over Takam, many are regarding this as hardest fight of the Brit's career after his Wembley match-up against Wladimir Klitschko in April 2017.
Parker, on the other hand, is fighting in the UK for the second time and despite this being the third defence of his WBO title, he remains a big underdog. He claimed the vacant belt over Andy Ruiz Jr. back in Dec. 2016.
When is the fight?
The fight takes place on Saturday, March 31. However, in Parker's home country, it will be April 1 by the time the first bell rings.
Are there tickets available?
There are very few tickets remaining for the fight and they are all currently priced at £40. These are available on the event's official ticket provider StubHub.
The £60, £80, £100, £150, £200, £300, £600 and £2000 VIP tickets have all sold out.
What time does it start?
The fight is scheduled to start at 10.30pm BST with the ringwalk expected around 10.10pm. However, as ever with boxing, this may alter depending on the length of the undercard action.

Who did they each beat last time?
Joshua's last fight was against late replacement Takam back in Oct. 2017, where the Watford boxer went on to win via 10th round stoppage. He was initially scheduled to face IBF mandatory challenger Kubrat Pulev, but the Bulgarian fighter withdrew.
Parker's last outing was in Sept. 2017 where he faced Hughie Fury -- cousin of Tyson -- in Manchester, UK. He successfully defended his WBO world title against Fury, claiming a controversial majority points victory after 12 hard rounds.

What is at stake?
Joshua puts his IBF and WBA heavyweight world titles on the line, while Parker's WBO belt is also up for grabs. The winner will also claim Joshua's IBO belt, despite it being widely regarded as not a legitimate world title.
