British boxer Tyson Fury will defend his Commonwealth title against Neven Pajkic in Manchester next month.
Both fighters will put their unbeaten 16-bout records on the line in the fight at EventCity on Saturday, November 12.
Pajkic's promoter, Rick Smiciklas, remarked that there is no love lost between the pair.
"I've never seen Neven show this much anger towards any other fighter," said Smiciklas.
"It all started when Tyson called out Neven, who then flicked his towel at Tyson, and it's grown from there.
"Neven can't stand Tyson. Calling it a bitter rivalry is weak. Now, they can settle their bad blood in the ring."
Pajkic, 34, was born in Bosnia but moved to Canada in 1996 where he is his adopted county's reigning heavyweight champion.
