Australian Rugby League Commission appoint Deloitte to audit Manly Sea Eagles' sports science unit The NRL has today dispatched private investigators to scour Manly and Penrith's records of supplement purchases in the wake of the Australian Crime Commission's inquiry into doping offences. Auditors from private accounting firm Deloitte visited Sea Eagles HQ at Narrabeen this morning with a brief to investigate the club's sports science department. A separate team of auditors arrived at Centrebet Stadium around 10am to complete a three-hour investigation of Penrith's records. It is not yet known whether other clubs are also being investigated. The concerns over Manly relate to sports science guru Stephen Dank, who provided supplements for the players between 2006 and 2010. Dank also consulted for Penrith in early 2011, but is believed to have concentrated primarily on the supply of GPS equipment. Dank is now at the centre of the ACC investigation after being sacked late last year from Essendon, who this week rocked Australian sport by announcing it had volunteered doping records to the AFL and ASADA. Dank also consulted for AFL outfits Gold Coast Suns and Geelong, as well as NRL teams Cronulla and Penrith.
