Collingwood president Eddie McGuire fears an AFL interchange cap rule change could lead to PED usage

COLLINGWOOD president Eddie McGuire says he is concerned that changing the rules around interchange rotations could lead to AFL players using performance-enhancing drugs.

The AFL currently caps interchanges within a game to 90, a figure introduced in 2016, after introducing a cap of 120 in 2014.

But McGuire is worried that if an even stricter cap is put in place, it could see some AFL players consider taking drugs like the peptide EPO (erythropoietin, a hormone that is believed to increase oxygen absorption, reduce fatigue and improve endurance).

EPO is banned by the World Anti-Doping Agency. The drug became well known when Lance Armstrong was stripped of his seven Tour de France titles for his use of both EPO and blood doping.

“I think the AFL have got to be careful,” McGuire said on Triple M.
