In boxing action Thursday, former heavyweight champion Michael Moorer was well behind on all 3 judges' scorecards when he scored a one-punch knockout over former cruiserweight champion Vassiliy Jirov.

Moorer, taken to a hospital for a shoulder injury after the fight, floored Jirov with a left hand in the ninth round. Jirov staggered up during the count, but referee Pat Russell waved the fight off as Jirov struggled to maintain his balance.
