We're going to get started this evening at 7 p.m. EDT with Yahoo! Sports' live stream of the off-television, pre-HBO pay-per-view undercard of Mayweather vs Ortiz from the MGM Grand in Las Vegas.
There will be five fights before the HBO PPV broadcast beings at 9 p.m. EDT, and we'll have coverage of each and every one of them. We will also have a thread later for the pay-per-view undercard (Canelo Alvarez vs Alfonso Gomez, Erik Morales vs Pablo Cesar Cano, and Jessie Vargas vs Josesito Lopez), and then a separate thread for the main event itself.
Here's what you'll see on this live stream, which has some interesting matchups:
Welterweights, 10 Rounds
Said Ouali (28-3, 20 KO) vs Carson Jones (31-8-2, 21 KO)
Ouali, 32, is a Moroccan-born fighter in the Mayweather Promotions camp who has been on Floyd's PPVs before, in a one-round brawl on the Mayweather vs Mosley card against Hector David Saldivia. Jones, 25, is a young veteran who has been around the block and was supposed to be Antonio Margarito's original pre-Pacquiao comeback opponent last year before that fell apart. He has recently worked with Canelo Alvarez during the young Mexican's camp. I like this fight a lot, and think it could be a really good one.
Super Middleweights, 8 Rounds
Marco Antonio Periban (14-0, 10 KO) vs Dhafir Smith (24-21-7, 4 KO)
A fight that could be low-risk or high-risk, depending on how you look at it. Periban, 26, is a power puncher, but struggled in his last fight, a UD-8 win over Alfredo Contreras. Smith, 28, has little power, but is generally durable and basically put the nail in Jeff Lacy's career coffin with a win over him last December.
Lightweights, 8 Rounds
Anthony Crolla (21-2, 9 KO) vs Juan Montiel (5-4-3, 2 KO)
Crolla, 24, is a Manchester fighter making his U.S. debut. He was Erik Morales' first of four scheduled opponents for this card, but then the WBC put up their vacant junior welterweight belt, and Crolla didn't fit the bill. He gets an easy consolation fight instead.
Super Middleweights, 6 Rounds
Adonis Stevenson (14-1, 11 KO) vs Dion Savage (11-1, 6 KO)
Savage, 24, is another Mayweather fighter. His loss came via KO-1 against Periban in February. Now he faces Stevenson, 33, a Haitian import to Quebec who has shown talent and his own shaky chin in the past.
Super Featherweights, 4 Rounds
Kyrone Butler vs Cassius Clay
Both are making their professional debuts.
