THE AFL will gather 18 clubs in a mid-season concussion workshop this week to assess and evaluate its concussion management policies.

Doctors, football managers and the AFL's medical directors will attend the workshop to discuss how to fine tune the processes in place and give feedback about what is happening in real time at football clubs.

The meeting is timely given the discussion surrounding the future of Brisbane Lions' champion Jonathan Brown, who missed last night's game against the Dockers in Perth after receiving a head knock against the Giants last Saturday.

Many commentators have called for Brown to give the game away as he has been subjected to several head knocks during his stellar career.

However, the Lions are leaving any decision in Brown's hands.

The AFL's football manager Mark Evans said the workshop was designed to ensure the competition's strong focus on managing concussion continued.

"We take the issue of concussion in sport extremely seriously and have shown a commitment to mitigating risks and increasing our knowledge about the issue for a long time," Evans said.

"We have been advised not to rush to judgement but to allow for the experts to conduct the long term research necessary to better understand concussion and its potential health effects for sports people.

"At the same time, the AFL has implemented rule changes, updated management guidelines and education to minimise the incidence and impact of concussion in football at all levels."

The AFL revised its concussion management guidelines in November to match recommendations from the 2013 Zurich Concussion Conference.

It argues that its approach has been cautious, with rule changes and education accompanying the updated guidelines.

Significant investment has been made towards research into concussion and mild traumatic brain injury.

AFL Medical Director Dr Peter Harcourt said the AFL constantly reviewed its concussion management practices.

"Concussion in sport is a very complex issue and at this point no one has all the answers," Dr Harcourt said.  

"There are a range of views about how it can best be diagnosed, how it should be treated, and what health impact it might have in the longer term."

The issue of CTE (chronic traumatic encephalopathy) has dominated discussion in America's NFL and it is on the radar of the AFL. Boston University's Chris Nowinski, considered an expert in the area, spoke in Australia last season and also addressed the AFL Players' Association.

Harcourt welcomes the discussion.

"We make no apologies for adopting a conservative view of the research conducted globally to date and its potential relevance to Australian Football," Harcourt said.  

"We continue to have an open mind and will continue to take on-board all research findings as we enhance our understanding of this complex issue."

AFL medical directors will also attend a global discussion conference in New York in August, with several of the world's sporting codes represented.
