Rumoured betting on the Manly-Souths game in round seven at Brookvale Oval is now being investigated by the NRL.
NRL chief executive David Gallop last night confirmed the probe was taking place.
"It is being said that two players conspired to ensure one of them scored the opening points in a game," Gallop said.
"We have a policy of following up any rumour about this sort of thing.
"We have spoken to both clubs and the Department of Gaming and Racing "We have found nothing to suggest this is anything but a rumour at this stage."
A number of betting agencies were contacted by the NRL who report there were no anomalies in any of their transactions on that game won 28-20 by the Sea Eagles.
Speculation has been rife regarding the performances of specific players .
South Sydney chief executive David Tapp denied any knowledge of the investigation initialy.
"I know nothing of it,"Tapp said.
After being contacted by the NRL,David Tapp revised his statement.
"Obviously David Gallop has now filled me in," Tapp said.
"Certainly we have spoken to one of our players about the issue and he absolutely, categorically denies any knowledge of it whatsoever.
"At this point in time they are unsubstantiated, unfounded rumours."
Manly media officer Peter Peters said he was contacted by the NRL over the issue yesterday.
"All we know is that it is a scurrilous rumour without any foundation," Peters said.
"It has been around for about a month and the players don't deserve to have those things said about them."Like
