Social media has been awash with beef between the pair for some weeks now and Whyte eventually landed the fight he wanted a few days ago.
Lifting the lid on what held up the negotiations, Whyte claims Browne continually moved the goalposts and stalled on making the deal before signing on for the spring with no time to spare.
“I can’t wait, I hate Lucas Browne and I want to hurt him,” said Whyte. “He’s said some nasty things and he’s going to have to pay for them.
“I don’t think he really wanted this fight. A deal was in place before then he started to try and change the terms. He kept delaying things after we gave in to his demands and started saying there was a fight in America he was chasing. We’ve bent over backwards, and up till now, he’s been more interested in making excuses than taking the fight.
“It’s been frustrating but we’ve finally got over the hill now so let’s go.
“He’s a big guy with an unbeaten record so you have to rate him a bit. He carries some power. You have to respect Heavyweight power, it only takes one punch.
“I’m not overlooking Browne, I’m focused on going to town on him. If I don’t knock him out, I will not be happy.
“The plan is to beat Browne and move closer to a World Title shot. Beating him should make me a mandatory challenger for a World Title – I’m highly ranked across the board, I’ll be a more than credible World Title challenger.
“I’ve been building my way up so we’re set for a big year,” he added.
Whyte v Browne will have the WBC Silver title on the line and could potentially mean the victor would be just one win away from a challenge against WBC ruler Deontay Wilder.
