Mike Tyson has been bruised and battered for so long, in a career that has threatened to waste away, that he has looked a candidate to join the fallen idols of the ring in boxing’s Babylon. This weekend he has the last chance at a redemption that he arguably does not deserve when he meets Lennox Lewis for three versions of the world heavyweight title at the Pyramid in Memphis. The fight will generate more than -million and will therefore be the richest in the sport’s history.
