Instead, Russia's Sultan Ibragimov easily outpointed Shannon "The Cannon" Briggs for the WBO title Saturday night. Ibragimov's quick left hands dominated the listless Briggs to earn a 12-round decision. "Tonight I will go to sleep as champion and will wake up as champion, and we'll see what happens after that," the 32-year-old Ibragimov said. What happened for Briggs was simple: nothing. more info.

Briggs wasn't nearly busy enough, didn't throw nearly enough punches and didn't seem to want it badly enough, either. It cost him the WBO heavyweight title he won less than seven months ago. All three judges had Ibragimov a clear winner: 119-109, 117-111 and 115-113. The Post saw it 117-111 for Ibragimov (21-0-1). Briggs, who battles asthma, said he was on medication that compromised his training. more info.

The southpaw Kirkland knocked down Duran within the first 20-seconds of the fight with a right hook behind the ear. The stunning blow dropped the African to the deck but he was able to beat the count and managed not only to survive the opening stanza but also bang with the talented lefthander for the remainder of the contest. more info.
