Several sources within the United States, and Mexico, are advising BoxingScene.com that WBC silver welterweight champion Josesito Lopez (30-4, 18KOs) will be announced, likely tomorrow, as the opponent for WBC 154-pound champion Saul "Canelo" Alvarez (40-0-1, 29KOs) on September 15th at the MGM Grand in Las Vegas. At the moment, BoxingScene has not received confirmation on the exact weight - whether the fight is set for the full 154 or a catch-weight.

Last month, Lopez moved up to 147-pounds and broke the jaw of Victor Ortiz to secure a ninth round stoppage at Staples Center in Los Angeles. Ortiz was the scheduled opponent to face Canelo in September.

Lopez weighed 144-pounds for the fight with Ortiz, and most expected him to get overwhelmed, but he managed to hold his own and went to war with Ortiz for nine rounds. Canelo is a small junior middleweight - but he is still bigger and stronger than Ortiz, so the weight will be the most significant factor against Lopez.

Showtime will televise the contest.

On the undercard, Jhonny Gonzalez (52-7, 45KOs) will defend the WBC featherweight title against Daniel Ponce De Leon (43-4, 35KOs).

Also, heavyweight contender Seth Mitchell (25-0-1, 19KOs) will take on Johnathon Banks (28-1-1, 18KOs).
