Adonis Stevenson vs Tommy Karpency results, LIVE fight coverage of PBC 'Friday Night Lights Out'

Al Haymon's Premier Boxing Champions (PBC) series continues its effort to bring free televised boxing to the public tonight (Fri., Sept. 11, 2015) with a Light Heavyweight title fight as mega-punching Adonis Stevenson defends his WBC belt against Pennsylvania's Tommy Karpency in Toronto, Ontario, Canada.

MMAmania will deliver LIVE coverage of "Friday Night Lights Out," starting with the Spike TV at 9 p.m. ET.

Stevenson (26-1, 21 KO) has won 13 straight, 11 by knockout, since a later-avenged 2010 loss to spoiler supreme Darnell Boone. This will be his fifth defense of his belt, which he won with an upset knockout of Chad Dawson in 2013.

Karpency (25-4-1, 14 KO) came up short in his title bids against Nathan Cleverly and Andrzej Fonfara, but became a surprise contender by upsetting the remains of Chad Dawson last year. He also recently fought a guy on a seven-fight losing streak in an eight-round fight, so make of that what you will.

The far-more-competitive co-main event pits U.S. Olympian and top prospect Errol Spence, Jr. (17-0, 14 KO) against his stiffest test to date: (23-1-1, 12 KO) Chris van Heerden, who has won nine straight.
