Former IBF world heavyweight boxing champion Charles Martin has called out Joseph Parker and Anthony Joshua in an expletive-laden rant.

Martin lost the IBF heavyweight world title to Joshua in April, after being knocked out in the second round of what was his first defence.

Martin's reign as champion was the second shortest in professional boxing history, lasting just 85 days.

The 30-year-old hasn't fought in a professional bout since, but claims he isn't done with the heavyweight division.

Martin called out both Parker and Joshua for potential fights in an unbelievable outburst uploaded to BOXINGEGO's YouTube channel.

In the four minute video Martin calls out Joshua and Kiwi WBO world champion Parker, asking for a fight on the same night.

"So Joseph Parker, I'm gonna whoop your a** and I'm gonna whoop your a**, Anthony Joshua, on the same night.

"Mark my words."

Martin also swears repeatedly and dons a balaclava with sunglasses on top while showing off his money in another rant unrelated to boxing.

Martin won the IBF world title by beating Ukraine's Vyacheslav Glazkov in New York in January, before losing the belt to Joshua in London in April, his first defeat after 25 professional fights.
