This weekend’s action kicks-off Friday night at Ricoh Coliseum in Toronto with the Premier Boxing Champions (PBC) series on Spike TV, headlined by a 12-round world light heavyweight title fight between defending WBC World Champion Adonis “Superman” Stevenson (26-1, 21 KOs) and upset-minded challenger Tommy “Kryptonite” Karpency (25-4-1, 14 KOs).

Also The Ring magazine and lineal 175-pound champion, Haiti-native Stevenson is a Canadian fan favorite who lives in Montreal.  Karpency, fighting out of Adah, Pennsylvania, hopes to parlay his stunning upset by decision last October of “Bad” Chad Dawson, who, ironically, Stevenson defeated in 2013 by first-round knockout to originally capture his world title belt.  In the 10-round co-feature, 2012 U.S. Olympian Errol Spence (17-0, 14 KOs) – recognized as the future of the welterweight division – faces the toughest test of his young professional career, South African invader Chris “The Heat” Van Heerden (23-1-1, 12 KOs).

On the same night at The Cosmopolitan in Las Vegas, two-time Mexican OlympianOscar Valdez (17-0, 14 KOs) faces challenger Chris “The Hitman” Avalos (26-3, 19 KOs) in the 10-round main event.

Headlining on the live truTV broadcast, Valdez is in the latest wave of standout Mexican fighters, while Lancaster, California’s Avalos has an experience advantage having fought Chris Frampton for a world title earlier this year in a losing effort.  The 10-round co-feature showcases sons of famous former boxers as defending USBA junior middleweight champion Jesse Hart (17-0, 14 KOs), of Philadelphia, puts his crown on the line versus Aaron Pryor, Jr. (19-8-1, 12 KOs), of Cincinnati.  Hart is trained by Philly great, “Cyclone” Hart, while Pryor is the son of Hall-of-FamerAaron “Hawk Pryor.

Saturday afternoon switches to Foxwoods Resort Casino in Mashantucket, Connecticut with PBC on NBC.  In the 10-round main event against Australian middleweight Michael “Pretty Boy” Zerafa (17-1, 9 KOs), former WBO middleweight champion Peter “Kid Chocolate” Quillin (31-0-1, 22 KOs) risks a planned All-Brooklyn title fight this December against  WBA “regular” championDaniel Jacobs.

Quillin has everything to lose and Zerafa, who will be making his U.S. pro debut, is all in with nothing to lose.  Ageless IBF junior middleweight champion Cornelius “K9” Bundrage (34-5, 19 KOs), of Detroit, defends his title against favored No. 1 contender Jermall Charlo (21-0, 16 KOs), of Houston, in the 12-round co-feature.

The weekend concludes Saturday night at MGM Grand in Las Vegas with an explosive Showtime PPV card, featuring three world title fights in the four-fight Throwdown Fantasy Boxing group.

WBC and WBA super welterweight champion Floyd “Money” Mayweather, Jr. (48-0, 26 KOs) faces two-time world welterweight champion Andre Berto (30-3, 23 KOs) in the 12-round headliner, which Mayweather claims will be the last of his incredible career.

Mayweather, fighting once again at home in Las Vegas, with a victory will tie the late, great Rocky Marciano for the greatest record upon retirement.  Whether or not Mayweather will come back to break the record remains debatable, but 2004 Haitian Olympian Berto, who fights out of Winter Haven, Florida, vows to silence his many critics.

WBC super featherweight champion Roman “Rocky” Martinez (29-2-2, 17 KOs) defends his title belt in a Puerto Rico vs. Mexico rivalry fight, respectively, against the same opponent he took it from, five-time, two division world champion Orlando “Siri” Salido (42-13-2, 29 KOs) in a potential war that isn’t expected to last the full 12 rounds like their first fight did this past April.

Former IBF junior middleweight champion and Las Vegas native, Ishe “Sugar Shay” Smith (27-7, 12 KOs), and 2004 U.S. Olympian Vanes “Nightmare” Martirosyan (21-2, 16 KOs) square off in an interesting 10-round bout.  Smith starred in the original The Contenders reality television show, while the Armenian-born, Glendale, California resident Martirosyan is a past world title challenger.

Rounding out this week’s Game Group fights is a 10-round super featherweight throwdown between three-time, two-division world champion Jhonny Gonzalez (58-9, 49 KOs), the Mexican knockout artist, and Puerto Rican Jonathan “Polvo” Oquendo (25-4, 16 KOs) in another powerful ethnic rivalry match up.
