Kaddour was voted back[8] into the quarterfinals after Juan de la Rosa pulled out – a tactic by Jesse Brinkley, Anthony Bonsante, Peter Manfredo, and Joey Gilbert designed to get under Smith's skin.

[citation needed] The first of the Contender contestants to fight again after the show's finale, Kaddour dominated through an 8-round unanimous decision against Maxell Taylor on July 22, 2005, on Showtime's Shobox.

Valverde, who had gone the distance with future world titlists Carlos Quintana, Kermit Cintrón, and Yuri Foreman, as well as other top competition, was the busier fighter, but Kaddour was the more effective puncher.

[citation needed] After an almost 3-year hiatus from boxing working a steady job, Kaddour appeared on the undercard of Danish Super middleweight Mikkel Kessler's defense of the WBA title at the Messecenter Herning, Denmark, September 12, 2009, winning a unanimous decision over the tough German, Mike Ermis.

Kaddour trained with Greg Coverson at the "Detroit Boxing Jungle" before scoring a 5th-round TKO over Vance Garvey at the Motor City Casino on October 6.

[citation needed] In August 2012 World Boxing News spoke with both Ishe Smith and Alfonso Gomez about possible rematches with Kaddour, giving him the opportunity to avenge his only 2 losses.
