THE AFL will ban sports science staff from injecting players at clubs.

That is the vow of AFL chief exectutive officer Andrew Demetriou.

As part of its crackdown on performance and recovery methods in the wake of the Australian Crime Commission’s explosive investigation into drugs in Australian sport, Demetriou will limit what injections can take place and move to ensure only club doctors administer treatments.

"There is an audit going on of all supplements," Demetriou told News Limited.

"We have got our AFL medical officers sitting down with club doctors, reviewing practices, particularly use of external people.

"There is going to be a restriction on the use of injections.

"There will be a ban on the use of IV at clubs, not just on game day.

"We are implementing some very, very serious measures to restore the treatments of players under one person and that is the club doctor."

Demetriou said the League had would help clubs identify and weed out "rogue elements" in the sport.

"There are vulnerabilities at clubs in relation to performance-enhacing drugs, illicit drugs, match fixing and organised crime," he said.

"We have talked about a road map of things that you should look for at clubs, things like ex-players, anti-ageing clinics, gyms, tattoo parlours.

"We have drawn a line in the sand.

"We are going to put a stop to rogue elements at clubs and the insidious nature of some individuals who are trying to spoil it for the rest of the code.

"It is only a handful of people but it can cause significant damage."
