Adonis "Superman" Stevenson (21-1, 18 KO's) lived up to his name Saturday night at the Bell Centre in Montreal with a spectacular upset victory as he defeated the favored Chad Dawson (31-3, 17 KO's) by 1st round knockout. Not much happened in the fight until a powerful right hand from Stevenson landed flush on Dawson's chin sending him crashing to the canvas. Dawson managed to get up but the referee didn't allow him to continue.
To open the card, highly regarded Yuriorkis Gamboa defeated Darley Perez by UD in a non-crowd pleasing fight. Scored were 116-111, 116-111, and 115-112.
