The AFL is likely to investigate the incident that left Hawthorn's Mitchell Lewis with concussion from a boxing session gone wrong.
7NEWS' Tom Browne revealed the AFL Players Association has already raised the incident to the AFL and the Hawks personally informed the AFL about the injury.
According to Browne, Hawthorn players were not told to target the head in the training session and AFL will now consider whether clubs should use boxing in their training sessions at all.
The AFL could ban boxing as part of an overhaul to reduce the likelihood of concussion and the prospect of class action taken against clubs and the league.
According to The Herald Sun's Marc McGowan, Hawks players did not wear headgear when Lewis' sparring partner Jacob Koschitzke knocked a ducking Lewis out with an uppercut.
Hawthorn coach Alastair Clarkson said on Friday night that boxing was part of the Hawks' weekly training program.
“We were doing some sparring on Monday and Mitch zigged when he should have zagged and got a knock to his scone, so hopefully he’ll be OK for us to play next week,” Clarkson said post-game on Friday night.
It is understood the Hawks record the boxing sessions as a precaution in case something goes wrong.
