The AFL is meeting with club doctors to work out how to better manage player concussions during matches.

It follows a league investigation into Geelong’s management of Allen Christensen, who was back on the field only a few minutes after receiving a knock during the loss to Gold Coast last weekend.

AFL football operations manager Mark Evans said its medical officer Dr Peter Harcourt had already met with the Cats medical staff.

Concussion has become a major issue in contact sports worldwide.

“One of the issues as an industry we have to try and get to a better place with is the consistency of the management around onfield incidents, that may or may not have involved a concussion,” Evans said.

“Diagnosis of concussion is difficult and best left to an expert.

“It’s sometimes easy to call something from the armchair when you don’t have all the information.”

Brisbane key forward Jonathan Brown, one of the greatest players of the modern era, retired on Monday after being concussed against Greater Western Sydney earlier this month.

It was the third heavy knock to his head in the last 12 months.
