By Dan Ambrose: Former WBA lightweight champion Brandon Rios (31-2-1, 23 KO’s) has reported tested positive for a banned substance following his one-sided 12 round unanimous decision loss to Manny Pacquiao (55-5-2, 38 KO’s) last month in Macao, China. According to RingTV, Rios tested positive for the drug methylexanamine, which is used as a dietary supplements. The drug showed up in Rios’ urine after the fight.
A drug like this could be used for a fighter to try and make weight if they’re having problems cutting weight. Rios reportedly struggled to get down to the 147 lb. limit after having put on a great deal of weight following his defeat against Mike Alvarado in March of this year. That fight took place at 140, but Rios rehydrated up to close to 160 after the weigh-in.
By Chris Williams: It looks like Manny Pacquiao’s fight against Brandon Rios (31-2-1, 23 KO’s) did worse than many people expected to on HBO pay-per-view. The fight, which Pacquiao’s promoter Bob Arum placed at the Cotai Arena, Venetian Resort, Macao, Macao, S.A.R., China, reportedly did between “490,000 to 510,000, according to ESPN. This is way lower than what was expected. That’s even lower than the 660,000 buys that Pacquiao’s fight against former Top Rank stable fighter Joshua Clottey brought in back in 2010. 
By Dan Ambrose: Brandon Rios (31-2-1, 23 KO’s) seemed to get upset with the questioning from HBO’s Max Kellerman last Saturday night moments after Rios had been beaten badly by Manny Pacquiao (55-5-2, 38 KO’s) by a 12 round unanimous decision at the Cotai Arena, Venetian Resort, Macao, Macao S.A.R., China. Rios lost about as bad as a fighter can lose when it comes to a decision, and he wasn’t a happy camper moments after the fight when the judges scores revealed that he had lost by the scores 119-109, 120-108 and 118-110.
By Gerardo Granados: It was great to see Manny Pacquiao (55-5-2, 38 KO’s) back in the ring last night in beating Brandon “Bam Bam” Rios (31-2-1, 23 KO’s) by a 12 round unanimous decision in Macao, China. His performance was really good but I won’t let myself to be influenced by his loyal fans and fellow writers who believe he is already ready to face Floyd Mayweather Jr. 
by Jordan Capobianco: No one ever said Mike Alvarado should fight Floyd Mayweather. Of course, Mike Alvarado is not named Manny Pacquiao. He’s not the only boxer in history to have won world championships in 8 weight classes. He isn’t a politician or a statesmen or a role model for a nation, and he isn’t the guy who knocked out Ricky Hatton with a killer head shot. He just isn’t Pacquiao. So when Alvarado beat up Brandon Rios, no one called for Alvarado/Mayweather. For people who aren’t Pacquiao, beating Rios has nothing to do with Floyd Mayweather.
By Carlos Gonzalez: Manny Pacquiao (56-5-2, 38 KO’s) is back. He clearly defeated on the cards Brandon Rios (31-2-1, 23 KO’s) by a 12 round unanimous decision this Saturday night in Macao , China. The judges very accurately scored the fight 120-108, 119-109, 118-110 in favor of Manny, who still is without any doubts one of the best pound for pound boxer in the business. 
By Chris Williams: In a card filled with mismatches from top to bottom, 34-year-old Manny Pacquiao (56-5-2, 38 KO’s) defeated fellow Top Rank stable fighter Brandon Rios (31-2-1, 23 KO’s) by a 12 round unanimous decision on Saturday night in Cotai Arena, Venetian Resort, Macao, Macao S.A.R., China. The final judges scores were 120-108, 119-109, 118-110. 
By James Harrison: Our most recent memory of Manny Pacquiao (54-5-2, 38 KO) in the ring is of a face-down and unconscious fighter– frozen at the hands of arch-rival, Juan Manuel Marquez. There are experts and fans equally paralyzed in this moment that give him little chance of a return to “greatness” because of it.
