Belfast taxi driver Martin Rogan has caused a huge upset by beating Olympic gold medalist Audley Harrison points.
Harrison paid the price for a negative and lazy display that handed the aggressive and crudely effective Rogan victory on a plate.
The English boxer landed freely with his right hand in the second round but Rogan began roughing him up and stunned the Wembley southpaw with a crisp left hook in the fourth.
Occasionally scoring with the jab, Harrison invited the winner of Prizefighter One to hit him in the sixth, but barely threw a single punch in the seventh with Rogan connecting with a right uppercut.
The same shot sent Harrison, whose caution and constant holding prompted jeers from the crowd, reeling a round later and Rogan did enough to stretch his flawless record to 11 victories.
