His first match was held at Madison Square Garden on 27 January 2001, against Chris Morris. He won the match via knockout at 2 minutes and 22 seconds in the first round.
Vidoz kept up a solid winning streak before encountering Zuri Lawrence, a "journeyman" fighter who, while proficient in his defensive ability, lacks a modicum of talent with regard to hitting his opponents (he has failed to record even a single knockout throughout his 12 years in the ring). Lawrence was able to baffle Vidoz with his slippery movement in the ring and score a unanimous decision after eight rounds.
Vidoz bounced back with his next fight, registering a devastating knockout of Eduardo Sandivares at just under a minute into the fight.
Vidoz dropped out of serious contention with a ninth-round TKO loss to Russian boxer Nicolay Valuev on 9 October 2004 at the Messehalle in Erfurt, Germany.
On 6 June 2005, Vidoz captured vacant European (EBU) heavyweight title and IBF Inter-Continental title with a split decision over Timo Hoffmann. Vidoz followed this up with a victory over British fighter Michael Sprott, but his "Titanium Jaw" was later checked in a fight in July 2006 against Vladimir Virchis, who beat Vidoz by KO in the sixth.
After his loss to Virchis he rebounded with two more wins against Alexei Osokin and Antoine Palatis before losing to Virchis
one more time this time by unanimous decision.
He won two more fights against Zoltan Peto and Paul Butlin, winning both of them by knockout.
He faced Sinan Samil Sam for the vacant EBU (European) heavyweight title on 4 July 2008, but lost by majority decision. This fight was particularly strange, with the Manager of Samil screaming and bullying the judges at the end of the fight, to obtain a winning decision over Vidoz. He fought Matt Skelton for the vacant EBU European heavyweight title on 19 December 2008. He lost the fight after refusing to come out for round 10. In his most recent fight he defeated Tomasz Zeprzalka by TKO in the fourth round. On 18 December 2009, he fought Albert Sosnowski for the EBU heavyweight title but lost by unanimous decision after twelve rounds.
After his loss to Sosnowski he would go on to lose his next three fights to Claus Bertino, Alexander Ustinov and Kubrat Pulev. All of those losses came by decision.
He would go on to win his next two fights by decision against Gabor Farkas and Sandor Balogh. His most recent fight was on December 16, 2011, where he lost a decision to undefeated Matteo Modugno and has retired after deciding to hang up the gloves following the loss.
