Hall of Fame promoter Bob Arum has taken aim at his good friend Al Haymon once again in the media.

The legendary, nearly 90 years of age promoter was in London today to announce the upcoming fight between Amir Khan and his fighter Terence Crawford for the WBO welterweight championship on April 20th.

In various interviews Arum has blamed Crawford’s lack of quality opponents and resume on Premier Boxing Champions founder Al Haymon for not letting some of his top welterweights fight Crawford.

Speaking to Tha Boxing Voice today Arum said:

“Well, you know, I don’t think Haymon and PBC is doing a service for boxing. Every other promoter shares their fighters — put fighters in with the other guys’ fighters. There is never a problem as long as the fight is right. With Haymon it’s impossible. He keeps his fighters internally fighting each other. He doesn’t do great business with them. I don’t know where he’s coming from but that doesn’t help to grow the sport.”

He added:

“Haymon just keeps his fighters to himself. He won’t share his fighters like Eddie Hearn and Frank Warren. He really is a cancer on the sport.”

No venue has been named yet for Khan vs Crawford but it is expected hopefully over the next week.

The two front runners for the fight are the MGM Grand in Las Vegas and Madison Square Garden in New York.
