Manly coach Geoff Toovey welcomed an investigation into the NRL club’s sport science department on Thursday in the wake of the doping scandal which has engulfed Australian sport.

Independent auditors Deloitte, enlisted by the NRL, descended on the Sea Eagles’ Narrabeen training base on Thursday to go through the department.

Toovey was confident the club had nothing to hide and said it would assist the NRL in any way possible.

“It was a decision from the NRL and we’re fully participating and cooperating,” Toovey told AAP on Thursday.

“We’ll do whatever necessary to ensure the sport in general is as clean as possible. We believe that is a must in our sport.

“As far as we’re concerned we’ve never had a problem here and we follow all procedures and protocols that have been put in place by the league.

“That’s all I can probably say on it, because that’s all we know.”

Sport scientist Stephen Dank worked at Manly from 2006 until 2010 and last year was at AFL club Essendon who this week became the subject of an anti-doping probe over possible misuse of supplements.

Dank has denied any wrong-doing.

A former Manly player who was at the club during Dank’s time there said there was nothing suspicious about the supplements the team took during that period.

“There was nothing untoward that I remember and I was never asked to take anything that I didn’t know about, and I wasn’t injected with anything suspicious,” the player told AAP.

“It was all good when I was there, Danksy was a smart guy who knew what he was he was doing.

“I never came across peptides or anything like that.”

Sea Eagles chief executive David Perry released a statement expressing confidence the club would be cleared of any taint.

“The Manly Warringah Sea Eagles fully support and will cooperate with any investigations by the National Rugby League, Federal and State authorities,” Perry said.

“We applaud the Federal Governments efforts to improve the integrity of all professional sport in Australia and condemn unreservedly any use of illegal performance enhancing substances by players.

“We are unaware of any of these issues at our club or in the game.”

League officials have previously used Deloitte’s services, including during the salary cap scandal which engulfed the Melbourne Storm.
