Months later he fought Jesus Felipe Valverde to a draw due to a recurring stamina problem. Two of the judges scored the fight even and the third had Kaddour winning by two rounds. Two months after this, in November 2006, Ahmad had a rematch against Valverde, which he won by split decision on Versus. 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. After the fight during an on camera interview when asked about his stamina in the final rounds, Kaddour explained that he had to drop weight from 192 lbs to 148 lbs, and that he had been born premature which might effect one of his lungs, and the combination may have taken away from his work rate.
