Looks like we'll be getting Shane Mosley vs. Sergio Mora on September 18th at the Staples Center in LA. Alvarez-Hatton is possible for the undercard:

As previously reported, unbeaten junior middleweight prospect Saul Alvarez (32-0, 24 KOs) is being penciled in for the same card. Richard Schaefer, CEO of Golden Boy Promotions, is making moves for an impressive card which ties in with Mexican Independence Day. The event will be carried on pay-per-view.

One of the names being tossed around to face Alvarez, is Matthew Hatton, the younger brother of former champion Ricky Hatton. Matthew had been mentioned as an opponent for Alvarez in the past. He has a tough fight scheduled against Yuriy Nuzhnenko on July 16 in England. Matthew would have to win that fight to keep his name in the mix for Alvarez.
