The signing was announced at the Affliction: Banned public press conference at the Westfield Mall in Century City, California.
The Brazilian light-heavyweight was available to Affliction with the closure of the Canadian-based Hardcore Championship Fighting promotion. Nogueira had signed a three-fight deal with HCF, but was only able to fulfill one, a TKO victory over Todd Gouwenberg on February 1.
In February 2007, the 31-year-old was surprisingly knocked out in 23 seconds by Rameau Thierry Sokoudjou at PRIDE 33. Afterwards, Nogueira took a year off mixed martial arts to focus on boxing, winning a Bronze medal at the 2007 Pan-American Games before signing with HCF.
Nogueira competed ten times for PRIDE and recorded big wins against Dan Henderson and Kazushi Sakuraba.
Noguiera (13-3) is expected to compete on the undercard of Affliction: Banned at the Honda Center in Anaheim, California
on Saturday, July 19. The main card will air live on pay-per-view while the undercard will be televised live on Fox Sports Net.
