FILE - In this May 25, 1965 file photo, challenger Sonny Liston, right, lands a body blow to heavyweight champion Muhammad Ali in the first moments of their heavyweight title fight, in Lewiston, Maine. Just months before the 50th anniversary of the fight, which became one of the most controversial sporting events of the 20th century when Ali knocked out Liston less than two minutes into the first round, both pairs of gloves are going on the auction block for the first time. Heritage Auctions is offering them as a single lot on Feb. 21 in New York. The auctioneer expects they will sell for more than $1 million. Bidding will start at $500,000. (AP Photo/File)
