(AP) Adonis Stevenson retained the WBC light heavyweight title Saturday night at the Bell Centre when Tavoris Cloud failed to answer the bell for the eighth round after sustaining a cut over his right eye.
Stevenson (22-1) successfully defended the title he won in June with a first-round knockout of Chad Dawson.
Cloud (24-2), the former IBF champion, also was cut on the left eyelid in the opening round.
Stevenson, from Blainville, Quebec, is the only Canadian currently with a world title. He stung Cloud with a stiff left in the opening round that left the cut and swelling on his eyelid.
Cloud rebounded in the second, but the right-hander rarely used his right hand. That drew taunting from Stevenson, who twice stood before his opponent with his arms stretched out, daring him to throw a punch.
Stevenson's next fight is to be a mandatory defense against England's Tony Bellew, likely early next year.
On the undercard, former champion Jean Pascal stopped George Blades with three knockdowns in the fifth round in a light heavyweight fight. Pascal (28-2-1) used the fight as a tuneup bout for his scheduled match in January with fellow Montreal fighter Lucian Bute. Blades is 23-5-2.
"This does me an enormous amount of good," Pascal said after his first knockout since 2009. "I'm a guy with power, but it had been a long time since I knocked anyone out. Now, I'll go into camp with more confidence."
In a matchup of Colombian light heavyweights, Eleider Alvarez unanimously outpointed Edison Miranda in a 10-round bout to improve to 13-0. Alvarez had winning scores of 99-90, 97-92 and 95-94.
