Olympic gold medal winner Anthony Joshua (10-0, 10KOs) has been destroying the competition as of late, but heavyweight veteran Kevin Johnson (29-6-1, 14KOs) is confident the up and coming prospect will be unable to knock him out on January 31st at the O2 Arena in London.

Johnson is so confident that he plans to stake half his purse on a side agreement. If Joshua is able to make him knockout victim number 11, Johnson will donate half of his purse to a charity of Joshua's choosing.

"I want to make an agreement. If Anthony knocks me out I’ll donate 50 percent of my purse to one of his charities. And if he gets knocked out, he gives 50 percent to my charity. There’s going to be a knockout so let’s up the ante," Johnson told Daily Mail.

But Joshua said: "I do my charity work but I’ve got a professional job to do. I’ve seen boxers throw cash about but I want to leave that to one side."
