While injury rates overall are down in the AFL and AFLW, serious knee injuries remain a key problem for the women's game.
Concussion has become a key focus for sport, given the health impacts on current and retired players.
Melbourne premiership star Angus Brayshaw was forced to retire prematurely in February because of repeated concussions.
Several former AFL players are involved in looming legal action against the league, because of ongoing health problems they say stem from on-field head knocks.
The league's injury report on the 2023 AFL and AFLW seasons makes a point of outlining what action is being taken in concussion research and player safety.
"The AFL continues to invest in, and support, research into concussion," the league said in a statement.
"There have been more than 30 rule changes, and there are more than seven full time employees working at the AFL in this space, across research and education.
"In addition to the funding already committed, player (match review) fines accumulated across the season go directly into concussion research."
Under the AFL and AFLW concussion guidelines, the earliest a player can return to the field is 12 days.
That means a player with a concussion must miss at least one game.
The most common injuries in the AFL last season were hamstring strains, concussions, calf strains and illness.
For the AFLW it was concussion, ankle injuries, ACLs and shoulders.
Knee ACLs, or anterior cruciate ligaments, have been a key issue for the various women's football codes.
While the incidence of ACL injuries continues to drop in the AFLW, they remain a leading cause of missed matches - 5.44 games per club last season.
