EVANDER HOLYFIELD has refused to rule out a rematch with Mike Tyson. Holyfield, who retained his WBA heavyweight title when Tyson was disqualified for biting him on both ears on Saturday night in Las Vegas, could be forgiven if he never wanted to see Tyson again.

Holyfield told American TV channel CNN: "I would never say I would never fight him. Right now, he hasn't proven be can control his attitude. Time will tell. If time permits, and two years down the road Mike has proven he can control himself, and he's fighting . . . I would never say never."

The Nevada State Athletic Commission yesterday formally moved to cite Tyson for a violation of boxing rules. The commission voted unanimously to prepare a formal complaint against Tyson, who is provisionally suspended, and to have his purse cheque of Pounds 20 million made over to the commission pending final resolution of the case.

Nevada law allows the commission to withhold 10 per cent of the purse as a punitive measure. The commission is also expected to ban Tyson for at least a year. The final sanctions cannot be decided until Tyson is formally notified of the complaint. He has 30 days to prepare for a disciplinary hearing, but has already said he will waive that right.
