Gould not worried about stadium's

New South Wales rugby league coach Phil Gould says the sandy surface of Suncorp Stadium is safe and has expressed his sympathy for the ground's administrators.

Six players, including four Sydney Roosters, have suffered knee ligament damage since the stadium underwent a $280 million refurbishment before reopening last month.

Gould says the redeveloped Lang Park is a great stadium and he's sorry that the knee injuries have generated such negative publicity. A spokesman for Ogden IFC, the stadium's venue operators, says 20 cubic metres of sand has been removed from the field in response to safety concerns from the Rugby League Players' Association.
