A riled-up Frazer Clarke swore at Jeamie ‘TKV’ Tshikeva’s team as tempers flared at a testy weigh-in for Saturday’s British heavyweight title bout in Derby.

After both men hit the scales – Clarke at 19st 4lb (123 kg) and TKV at 18st 12lb (120 kg) – a fiery standoff erupted.

Words were exchanged and voices gradually rose, and security stepped in as tensions threatened to boil over.

Clarke then stuck both middle fingers up at TKV’s small entourage, reigniting the verbal sparring.

“I’ll take this boy to school and beat him up,” Clarke, 34, warned. The next time they meet will be at the Vaillant Arena, with the bout broadcast live on BBC Two.

The rivalry between the two Britons has intensified since their original October 25 fight was postponed because of an injury to TKV, which Clarke has publicly questioned.

“He’s a funny character. I walked past him in the corridor, didn’t do anything, but when security is around he wants to talk funny,” 32-year-old TKV said. “That really shows his character.”

The weigh-in was open to the public, with a couple of hundred fans packed into a hotel function room near East Midlands Airport.

Clarke left the stage but heckled from the floor, shouting “one round”, to which TKV shot back: “You carry on nodding your head and I’ll knock you out tomorrow.”
