Ex-Palace, Norwich striker McKenzie making waves in boxing
McKenzie on Saturday night won the second fight of his career when he outpointed Poland's Robert Studzinski over four rounds.
McKenzie first fought in June when he stopped John Mason after just two minutes and 44 seconds of the second round of his pro debut.
The super middleweight, who retired from football in 2011 after battling depression, was the chief support for Norwich welterweight Nathan Dale's fight against Michael Dufek. Dale, incidentally, comfortably outpointed Dufek over eight rounds and was awarded an 80-73 victory.
