The 24-year-old from Watford won Olympic gold at the ExCel last year, and is prepared for a rush of emotion when he steps out into the arena once again - this time in his fourth professional fight.
"This is where I learnt a lot, it is where I can say the heights of my amateur career happened," BoxRec News quotes him as saying. "I will never forget the Games and especially that incredible Sunday when I won the gold.
"I'm at the start of a fresh new chapter now though, the Olympics was amazing but it's in the past. I am loving life in the pro ranks and learning every day.
"Dorian is a tough test for just my fourth fight and he'll want to make a name for himself, as all my opponents do. I am grounded, I am focused and I am taking every fight very seriously."
Joshua has won all three of his previous engagements by knockout.
