Floyd Mayweather Sr. doesn’t want his son Floyd Jr. fighting the 172 lb. WBA/WBC junior middleweight champion Saul “Canelo” Alvarez (42-0-1, 30 KO’s) at 154 lbs. because he sees the potential of Canelo filling up on water weight in the 24 hours after the weigh-in and coming into the fight weighing well over 170 pounds in their proposed fight on September 14th.
As such, Floyd Sr. is saying that if Canelo wants to fight Mayweather Jr. it’s going to have to be at 147. Canelo will have to prove that he can make that weight before he can get the fight with Floyd Jr.
After seeing how exhausted WBA/WBC junior middleweight champion Saul “Canelo” Alvarez looked in his fights against Austin Trout and Shane Mosley, I think Miguek Cotto (37-4, 30 KO’s) has a good chance of beating Canelo in September if he ends up being the one that faces him, and right now it’s looking like Cotto could be the guy that gets picked. 
Top Rank promoter Bob Arum is saying that former IBF/WBO super bantamweight Nonito Donaire (31-2, 20 KO’s) will be back in the ring in either October or November this year against a still to be determined opponent. It won’t be newly crowned WBC super bantamweight champion Victor Terrazas because he’ll likely be facing newly signed Top Rank fighter Vic Darchinyan. 
Floyd Mayweather Jr’s team reportedly gave WBA/WBC junior middleweight champion Saul “Canelo” Alvarez the option to fight him at 147 lbs. on September 14th if he wants to get the biggest payday of his career. Canelo is only 22-year-old and has no pay per view history behind him to show that he’s a proven money maker. 
Manny Pacquiao (54-5-2, 38 KO’s) hasn’t had an easy fight since his one-sided 12 round unanimous decision win over a completely shot Shane Mosley two years ago in May, 2011. Since that fight, Pacquiao has gone downhill himself and looked bad in his two fights against Juan Manuel Marquez and his fight with Tim Bradley. 
WBA/WBC junior middleweight champion Saul “Canelo” Alvarez hasn’t fought at 147 in the 11 fights dating back to his win over a tiny Jose Miguel Cotto back in May of 2010, but if Canelo wants a fight against Floyd Mayweather Jr. then he’s going to have to find a way back down to that weight because that’s what he’s going to have to do in order to get the big payday fight he’s been harping about for ages. 
According to Steve Kim, Team Mayweather is saying that WBA/WBC junior middleweight champion Saul “Canelo” Alvarez will have to come down to 147 if he wants to fight Floyd Mayweather Jr. on September 14th. There won’t be a catchweight of 150 and Mayweather won’t move up in weight to fight Canelo at his weight of 147.
Brandon Rios (31-1-1, 23 KO’s) expects to make former 8-division world champion Manny Pacquiao (54-5-2, 38 KO’s) sorry for picking him to fight in their upcoming November 24th in the tax friendly [at least for Pacquiao] Macau, China.
Showtime Vice President of Sports Stephen Espinoza feels confident that the Floyd Mayweather Jr. vs. Saul “Canelo” Alvarez fight will take place on September 14th in Las Vegas, Nevada, as he says the negotiations between Mayweather and Canelo’s team are underway.
Vic Darchinyan (39-5-1, 28 KO’s) smashed his over-matched opponent Javier Gallow (18-7-1, 10 KO’s) in a 4th round TKO on Saturday night at the Uni-Trade Stadium, in Laredo, Texas, USA.
