Kubrat Pulev is a possible opponent for Joshua as the night's headline act at a venue and date yet to be announced. If confirmed, the Bulgarian, who has fought 24 times as a professional and has lost to only Wladimir Klitschko, will easily present Joshua with easily the tough fight of his career.
Incidentally, Pulev knocked out both Dimitrenko - Parker's next opponent - and Russian Alexander Ustinov, the man who finished David Tua's career, in the space of four months.
Whether the fight is in Manchester or Cardiff, the crowd will be big and loud, with a liberal sprinkling of celebrities. And it will be encouraged by the third big fight slated for the evening - English heavyweights Dereck Chisora v Dillian Whyte, two men who have made it clear they don't like each other - which is also likely to make the weigh-in interesting.
Parker's promoters Duco Events have seen how Samoan-born Australian Alex Leapai froze on the big stage in his title challenge against Klitschko in Germany two years ago, when Parker was on the undercard. They have also seen how David Tua struggled with the demands of his world title fight against against Lennox Lewis, despite being used to the bright lights of Las Vegas.
In association with Parker, his family and trainer Kevin Barry, Duco have put the 24-year-old on an accelerated learning plan throughout his four-year professional career. Fighting in the UK is the next step. There is an element of risk, but at least it will help to take the unknown out of the equation.
