Having settled 30 of the grievance claims made against the club by the 34 players suspended last season by the Court of Arbitration for Sport, Bombers CEO Xavier Campbell and his team have not yet managed to resolve their legal issues with three other former Essendon players including Nathan Lovett-Murray.

But they are understood to have become increasingly frustrated with Carlisle's advisers as they seek to move forward in 2017 and out of the shadow of the drug scandal that has haunted the club for four years.

Carlisle cut a disenchanted and embittered figure during his last season at the Bombers although in recent months his public comments have indicated he was keen to move on from the drugs saga.

Carlisle's manager Anthony McConville was not available for comment regarding the state of Carlisle's claim. The 25-year-old is being represented by former AFL Coaches Association lawyer Chris Pollard.

While it was revealed almost 12 months ago that Carlisle's legal team had linked his 2015 illicit drug use with the trauma of his final three years at Essendon no claim has yet been put to the club.

This means the player has to date gone without his playing wages for all of last season. Carlisle's four-year deal with St Kilda included a trigger for a fifth season and was worth more than $500,000 annually. St Kilda stopped paying Carlisle last January and did not start paying him again until the end of October. Over that period he worked part-time for three to four days a week for a commercial building firm with connections to the Saints, Buxton Constructions. Carlisle is still working there one day a week.

Sensationally caught on social media snorting a white substance just hours after being signed by the Saints, Carlisle was suspended for two weeks by his new club and made to forfeit $50,000 in marketing money. The suspension was served concurrently with his season-long ban and Carlisle returned to the AFL last week via St Kilda's first JLT pre-season game.

Lovett-Murray, 34, has been seeking advice from the AFL Players' Association and is understood to have lodged a large seven-figure claim against the Bombers through his manager Peter Jess.

The Carlisle issue has emerged as another aggrieved former player on Wednesday agreed to a settlement with Essendon.

Hal Hunter, the player who demanded via legal channels to see medical files documenting the drugs he was given by Essendon, is understood to have now cut all official and legal ties with the club in a settlement approved in court early on Wednesday. In March last year Hunter was ordered by the courts to pay Essendon's legal fees for seeking those files. That court order has since been reversed.

Hunter was not one of the 34 banned players but in an interview last year with Fairfax Media he said his diagnosed anxiety and depression stemmed from concerns about what drugs he had been given during 2013 at Essendon.

Banned last year from his player-coaching role at Rumbalara in Shepparton, Lovett-Murray like most of his former teammates has also taken on the club for breaches of duty of care and reputational damage.

Essendon has reached various settlements with all of the 12 players remaining at the club, including Jobe Watson who lost the 2013 Brownlow Medal as a result of his drug ban and new captain Dyson Heppell, a former Pollard client.

All players represented by Slater and Gordon have also settled with the club including Stewart Crameri who could have been a Bulldogs premiership player last year.

Paddy Ryder has also settled his claim with his former club.
