Michael Phelps should stay out of international competition until swimming's governing body FINA sorts out the chaos over swimsuits, according to his coach.

FINA has agreed to ban performance-enhancing polyurethane suits next year after a glut of world records but said the new rules may not come into effect until April or May.

Phelp's' coach Bob Bowman said: "He might do some local meets, but as far as trying to do anything during this (time) frame on this level, I think he'll be waiting. Enough is enough. I mean, come on."

He added: "This move to do it in April is unacceptable. It needs to happen January 1 if not next Monday."

Bowman said Phelps, who won a record eight Olympic gold medals last year and has sparked an upsurge of interest in the sport, had agreed "things should happen sooner rather than later".

Phelps was beaten in the 200metre freestyle final by Germany's Peter Biedermann, who broke Phelps's world record wearing an all-polyurethane suit.

Asked about staying out of future competitions, Phelps said he would abide by FINA's rules but Bowman made the decisions about where he would compete.

The new suits "have changed the sport completely. Now, it's not swimming. Now, the headlines are about who's wearing what suit," he said.

"FINA are going to make the decision, I can't make it for them. I'm going to finish the meet here and get ready for next year and for the London Olympic Games in 2012."
