Boxing champion-turned-actor Lennox Lewis was 'knocked out' by four chess masters last week as part of a board game bonanza in New York's Washington Square Park.

Lewis, who famously played chess to calm his nerves before a big fight, played 18 matches in a speed chess tournament and lost only four times.

The players who beat the champ each won $1,000 and a certificate boasting "I KO'd Lennox Lewis."
