Geelong CEO Brian Cook has welcomed any investigation by the AFL and ASADA in relation to the current drugs issue that has engulfed Essendon.

"The club is fully committed to assisting the AFL and ASADA in this investigation,"Cook said.

"We have nothing to hide and there has been no wrong doing on our part. The club’s doctors, and not any sport science staff, directly determine all treatments and the use of all supplements by players. No player has ever been requested to sign a waiver or indemnity concerning supplements used.”

The Cats have been dragged into the saga as current Essendon fitness advisor Dean Robinson worked with Geelong for three and a half years.
