Problems continued to pile up for the Bulldogs rugby league club with a report that a player tested positive for cocaine last year and was fined $25,000.

The Daily Telegraph said it knew the identity of the player but did not name him for legal reasons.

The player was caught in a club testing procedure.

Bulldogs chairman George Peponis declined to comment on the matter.

"Under the terms of our code of conduct, which all players sign, all matters relating to drug testing are confidential between the club and the players and, as such, I can't make any comment on that," he told the newspaper.

The club is not obligated to inform the National Rugby League of positive internal drug tests.

The NRL conducts it own testing and imposes minimum two-year bans for positive results.

The revelations followed the outburst by Bulldogs board member Peter Mortimer who blamed the immoral and stupid behaviour of some players in Coffs Harbour for the crisis enveloping the club.

An emotional Mortimer, speaking a day after his brother Steve quit as chief executive, also warned some players would "pay heavily" as a result of the alleged sexual assault of a woman in the NSW coastal town on February 22.

"There's no doubt some immoral things happened in Coffs Harbour," Mortimer said.
