In a recent Twitter fight, Conor Benn and Kell Brook make harsh remarks about one another

Conor Benn, a British boxer who was mired in controversy last year, did not have the best year. 

His highly anticipated battle against Chris Eubank Jr. had to be cancelled when the 26-year-old tested positive for a prohibited drug.

Yet, the WBC recently cleared Benn after accepting his justification for the illegal substance found in his system.

Due to this, Benn even made a suggestion that he will fight Manny Pacquiao, a previous eight-division champion. 

Benn was not afraid to criticise his opponent and said that Brook quit the sport the last time they attempted to get into a fight.

He also brought up their three-year-old sparring match, saying it must have had an impact on Brook. 

"The last time we attempted to provoke a fight, he opted to retire.''

He wrote, "Must have been that sparring session." But Brook also responded angrily, insisting that Benn was the one who ended the session.
