Furlan then fought US based Lebanese boxer Ahmed Kaddour, a former contestant on The Contender, the reality television series. The fight took place at Braunschweig, Germany. The fight went the full distance with Kaddour winning narrowly on points to inflict Furlan with the first defeat of his professional career.
After sixteen fights, Furlan fought in his first title fight when he faced Neapolitan Elio Cotena in July 2004 for the Italian Light Middleweight Title at the Toscolano Maderno, Turin.

Sylvester stated that Furlan "an iron head" and that there was little he could do that would stop Furlan and was surprised at the stamina of Furlan and the punches he could take.
Furlan's follow up fight, in May 2007, was a victory over Hungarian Attila Kiss.
Furlan was lined up to be the first opponent of what was being billed as "The Homecoming" of Irish fighter John Duddy in Dublin, Ireland. Furlan stated that he was going to spoil Duddy’s homecoming and upset his perfect record because he had spotted a weakness in Duddy's style and was going to expoilt that. Furlan was quoted as saying "“I have great respect for John Duddy but I will come with my own tactical plan to beat him. He is tough and not afraid of anyone so he’s just like me in that respect. I will be out to spoil his homecoming but I’ll buy Duddy a pint of Guinness afterwards to apologise for beating him!".
The fight was a keenly contested bout with both fighters suffering cuts. Duddy floored Furlan in the tenth round however Furlan rose to beat the count. Duddy sensed that Furlan was in trouble and piled forward and floored Furlan again at which point the referee stopped the fight with less than ten seconds to go in the fight.
