Washington:Boxing's most notorious ex-convict, Mike Tyson, will now be able to fight heavyweight world champion Lennox Lewis in Washington in June. Tyson had been barred from fighting in the boxing Mecca of Las Vegas for his bad behaviour after the two boxers had been involved in a brawl during a news conference in New York in January. Now less than a month after Nevada state officials rejected his bid to fight Lewis, Washington has stepped in and granted Tyson a license in what is expected to be the richest bout in boxing history. The three-member board of the Washington DC Boxing and Wrestling Commission has issued a preliminary ruling approving Tyson's request for a license that would allow him to fight Lewis on June 8 at the city's MCI Center. Thirty-five-year-old Tyson was all set to fight Lewis in Las Vegas in April for $150 million when the State Athletic Commission refused to renew his lapsed license. Since then Tyson has been trying to find another venue for the fight and has already been rejected by Texas and Georgia states.
