It seems the Nightmare, Diego Sanchez (21-4-0) will be staying at welterweight, despite a loss to John Hathaway at UFC 114 in April at his return from lightweight. Prior to the Hathaway loss, Sanchez also had a pulverizing loss to the former lightweight champ BJ Penn causing the TUF season one winner to return to welterweight.
Sanchez will look to get back into the winning circle October 23 at UFC 121 in Anaheim, CA against Paulo Thiago (13-2-0).
Thiago also recently suffering a loss against the hitman, Martin Kampmann by unanimous decision at UFC 115 in June. Prior to that Thiago was on a two win streak against Jacob Volkmann and Mike Swick.
UFC 121 will be headlined by heavyweight champion Brock Lesnar vs Cain Velasquez.
