After defeating the Worlds heavyweight champion, Kyotaro on December 5, 2009, Spong fought Jerome Le Banner in April 2010. Similarly to the Corbett fight, Spong broke his right hand in the first round and was knocked down. Despite coming back strongly, he lost by decision. At the end of the year, he qualified for the K-1 World Grand Prix 2010 Final, defeating veteran Ray Sefo in an elimination match, only to lose to eventual winner Alistair Overeem at the quarter final stage in what was a more competitive fight than most had predicted, as Overeem was much the bigger fighter. At the start of 2011, Spong had to vacate the It's Showtime 95MAX world title due to a number of issues, such as not having had a title defense in the allocated two years and his management stating that he had moved up in weight to fight as a heavyweight.
