Joshua and Parker agreed to put their IBF, WBA Super, IBO and WBO belts and unbeaten records on the line, following a period of intense negotiation between the rival camps.
Joshua was victorious on the day, after 12 rounds of boxing going to the judges score cards. Joshua now within touching distance of becoming the first undisputed Heavyweight champion of the world since Lennox Lewis in 1999.
For Parker, this is not the end. He has earned the respect of many British fans and promises to be back!
