The AFL has officially issued a "please explain" notice to the Geelong Football Club following the revelation of a controversial, secret agreement signed with premiership defender Jake Kolodjashnij regarding future concussion liability.

Under the terms of the secret 2024 deal, Kolodjashnij—who has a history of head knocks—consented to take on personal legal responsibility for any potential future brain trauma. The waiver was designed to shield the club and its medical staff from future legal action, raising significant ethical and legal questions within the sporting community.

Club Admits to 'Misstep'

Geelong chief executive Steve Hocking confirmed the AFL's official inquiry on Friday afternoon, taking responsibility for the club's failure to register the agreement with the league or the AFL Players Association (AFLPA).

"I take responsibility for the fact that we didn't lodge it with the AFL and the AFLPA," Hocking said. "I have received a letter of 'please explain' from the AFL in relation to this matter, so we'll deal with that over the coming days."

Hocking described the failure to report the deal as a "misstep" and stated that Geelong would fully cooperate with the league's investigation, adding that the club has already committed to stripping the liability waiver from Kolodjashnij's contract.

Kolodjashnij Breaks His Silence

Following intense speculation, the 30-year-old defender, who has played 209 games and was a key part of the Cats' 2022 premiership campaign, identified himself as the player at the center of the controversy.

In a statement released through the club, Kolodjashnij expressed frustration that his private medical circumstances had entered the public domain.

"While I appreciate the efforts made not to identify me, the speculation has left me feeling I needed to address this personally," Kolodjashnij said. "I participated fully in the AFL's independent concussion panel process, respected its independence, and was comfortable with the outcome. I have continued playing AFL football since."

"What disappoints me most is that my private medical information has been made public. Everyone deserves the right to keep their confidential medical information private. I am healthy, feeling good, and focused on playing my role for the team."

The issue of concussion is deeply personal for the Kolodjashnij family; Jake’s twin brother, Kade, was forced into an early retirement in 2020 after suffering repeated concussions during his career with the Gold Coast Suns and Melbourne Demons.

The Broader Concussion Crisis

The AFL has stated it is "satisfied" the side agreement was not used to clear an unfit player to return to the field, but the secret deal has nonetheless ignited fierce debate. New AFL Commission Chair Craig Drummond was the president of Geelong when the deal was struck, adding another layer of complexity to the league’s investigation.

The controversy comes at a highly sensitive time for Australian rules football. A growing list of modern stars, including Angus Brayshaw, Jeremy McGovern, and Paddy McCartin, have been forced into premature retirement due to the long-term effects of repeated head trauma.

Furthermore, post-mortem diagnoses of Chronic Traumatic Encephalopathy (CTE) in deceased champions like Danny Frawley, Shane Tuck, and Graham 'Polly' Farmer have heightened urgency around player welfare. The AFL is currently facing a monumental, multimillion-dollar concussion class-action lawsuit in the Supreme Court of Victoria, spearheaded by former Geelong defender Max Rooke, which is scheduled for trial next year.
