Singapore's reigning silat world champion Shakir Juanda has stumbled again in his quest for an elusive SEA Games gold medal.

The 25-year-old was beaten 0-5 by arch rival Le Si Kien of Vietnam in the semi-finals of Match Class H, consigning him to only a bronze medal - the same result he achieved two years ago in Palembang, Indonesia.

Le was the same opponent whom he had narrowly beaten 3-2 in the final of last year's silat world championships final in Chiang Rai, Thailand.

A controversial no-call in the second round, when the referee refused to give a warning to Le for a punch to Shakir's face, swung the bout the Vietnamese's way.
