KUALA LUMPUR: National champion Ivan Yuen has been ruled out of the World Squash Championships in Manchester next week due to a health-related issue.
Ivan, 27, has been sidelined since returning from the CCI International in Mumbai in early November after complaining of chest pains.
The World No 46 has been undergoing tests to discover the source of the problem and as a result missed the recent Hong Kong Open and the Men's World Team Championship.
Squash Racquets Association of Malaysia director of coaching Mej (rtd) S. Maniam is hopeful Ivan will be back playing next month.
"It has something to do with the muscle under the ribs close to the heart and we want to be doubly sure that he can return to play soon," said Maniam today.
"He is undergoing some tests over the next couple of weeks and he may be able to return in January, if all goes well."
In the initial draw for the World Championships, Ivan is scheduled to face top seed Gregory Gaultier of France in the first round on Sunday.
In Ivan’s absence, Nafiizwan Adnan and Ng Eain Yow will carry Malaysia's challenge in the men's event and eight-time world champion Nicol David in the women's.
Nafiizwan and Eain Yow arrived in Manchester after playing in Marseille at the World Team Championship where Malaysia finished 12th.
National No 1 Nafiizwan faces a qualifier in the first round with either ninth seed James Willstrop of England or India's Saurav Ghosal awaiting in the next round.
"Willstrop is favourite to win against Ghosal but he is beatable while Nafiizwan beat Ghosal in a very close five game battle in France," said Maniam.
"Eain Yow has to play in the qualifiers and must win three matches to reach the main draw but he is coming of age."
