Dutchman has chest muscle injury

ATHENS -- Australian Wayne Arthurs has been named to
replace Martin Verkerk in the men's singles at the Olympics
after the Dutchman was injured, organizers said on Monday.

Verkerk, who reached the final of the French Open last year,
was forced to withdraw because of a chest muscle injury.

Argentine Mariano Zabaleta is to replace No. 3-ranked
Guillermo Coria as the partner of the former Wimbledon finalist
David Nalbandian in the men's doubles.

Zabaleta had already replaced Coria in the men's singles
after he was ruled out with a shoulder injury.
