It comes as the boxing star is helping to train former UFC star Francis Ngannou ahead of his crossover boxing contest against Tyson Fury in Saudi Arabia on October 28
In the build-up to the fight, Tyson told Boxing Arabia podcast that some of his success could be down to fights being rigged in his favour. The 57-year-old went on to say he believes the tables were turned on him by his own promoter when he suffered a surprise championship belt defeat to Buster Douglas in 1990.
The fight between Tyson and Douglas was a 42-1 odd in Tyson's favour, but despite being knocked down by the champion in the eighth round, he was allegedly given a slow count by the referee and was able to recover. Tyson was then floored in the 10th round and although he was able to get back on his feet in time, the referee wouldn't let him carry on.
