Career
As of April 2012 he is the most successful mixed martial artist in Malaysian history with a professional record of 6-1. He began training in Taekwondo in Perlis at the age of 13 and later took up Muay Thai. Yeoh"s work as a school teacher took him from Perlis to Johor Bahru where he founded the first Mobile Marketing Association camp in the region in 2006.
Yeoh decided to enter Mayhem 2 which was organised as the promotion now known as Malaysian Fighting Championship in 2012.
Despite only being 145 lbs he beat Sam Chan and Raymond Tiew in the quarter finals and semi finals, Tiew would later go on to fight for ONE Championship. In the final he took on Kazbek Shalbassov but lost in controversial circumstances after the referee gave Shalbassov time to recover from an illegal knee which video replays proved to be legal.
On 10 December 2011 he stopped Malaysian Muhammad Taufiq Hashim with punches in the first round of their fight at Malaysian Fighting Championship 3. On 10 March 2012 he stopped another Malaysian, Mohd Zakhir, with a head kick 27 seconds into the first round of their fight at Malaysian Fighting Championship 4.This stoppage is proven to be controversial since his opponent can still fight and its only a knockdown.
Just two weeks later, on 24 March 2012, Yeoh defeated Singapore"s Zulkarnain Mohammad by triangle choke in the first round of their fight at Ultimate Mobile Marketing Association - Ultimate Fight Night 7.
On 14 April 2012 he took on another fighter from Singapore, Mamat Sparko, at Gods Football Club. In April 2012 he was strongly linked with ONE Championship and tipped to appear on their 23 June event at Stadium Negara in Kuala Lumpur something which Yeoh said would be a "dream". Yeoh was one of four fighters selected for the ONE Football Club Malaysian Featherweight Tournament and he defeated Raymond Tiew for the second time in his semi final matchup at ONE Fighting Championship: Return of Warriors which was held at Putra Indoor Stadium on 23 June and will face Jian Kai Chee in the final.
