The stoppage was controversial as Bajrami claimed to have been hit by an illegal elbow from van Esdonk and refused to return to his feet, prompting the doctor to deem him unable to fight.
He defeated Siniša Andrijašević by technical knockout in the quarter-finals when his opponent was not allowed continue on the advice of the doctor, and then faced Mirko Cro Cop at the semi-final stage.
At the K-1 World Grand Prix '99 opening round in Osaka, Japan on October 5, 1999, Bajrami had his first of three meetings with Dutch legend Ernesto Hoost, losing by unanimous decision.
After going 1-1 in the first half of the year with a decision loss to Stefan Leko at K-1 The Millennium in Osaka on April 23, 2000 and a points win over Samir Benazzouz at K-1 Fight Night 2000 in Zurich on June 3, 2000, Bajrami was invited to compete in the K-1 Grand Prix Europe 2000 in Zagreb, Croatia on September 1, 2000.
Following the sudden passing of his trainer Andy Hug in August 2000, Bajrami relocated to the Netherlands to train under Peter Aerts and Rene Rooze at Chakuriki Gym.
2002 was a quiet year for Bajrami as he competed just once under the K-1 banner, albeit taking three fights in one night at the K-1 World Grand Prix 2002 Preliminary Croatia on April 13 in Zagreb.
On March 6, 2004, Bajrami was crowned the ISKA World Super Heavyweight (+96.4 kg/212 lb) Muay Thai Champion when he beat Australia's Peter Graham by decision in his birth city of Pristina, Kosovo.
He knocked out Alessandro D'Ambrossio in the first round at the Night of Fighters 4 event in Bern, Switzerland[5][6] but then dropped a decision to giant Russian Alexander Ustinov in Moscow a month later.
He then TKO'd Dániel Török in November of that year in Sursee, Switzerland[7] before finishing American Mike Shepherd with a highlight reel high kick on June 27, 2009 in the same city.
