Swans rule out injured skipper Mills for grand final

Sydney captain Callum Mills won't play in the AFL grand final after the Swans opted not to risk the midfielder off a hamstring injury.

Mills missed the preliminary final win over Port Adelaide after suffering a minor hamstring strain at training on September 10.

He was attempting to prove his fitness to return to face the Brisbane Lions in Saturday's decider, just 18 days after sustaining the injury.

Wednesday's closed main training session was D-day for Mills, who had been challenged to train fully and put himself in contention.

While he had fronted media after the session and insisted he had trained at "100 per cent", the club soon afterwards ruled him out.

"Sydney Swans captain Callum Mills will not play in Saturday's AFL grand final," the club said in a statement.

"Mills trained this morning and after taking everything into consideration a joint decision was made by the club's medical staff and the coaches to rule him out."

Defender Robbie Fox appears likely to hold his spot as a result of Mills's absence.

Dane Rampe looms as the stand-in skipper who would lift the premiership cup aloft, and receive the newly-minted Ron Barassi Medal as premiership captain, if Sydney triumph.

Mills is the first captain to miss out on a grand final since GWS co-captain Callan Ward in 2019.

The quick decision also allows the Swans to focus firmly on the game, without the distraction of Mills's fitness as an ongoing narrative in the background.

Mills played just seven games in an injury-marred campaign.

The 27-year-old was ruled out of the first half of the season after tearing the rotator cuff in his left shoulder in a Mad Monday mishap last year, before a calf injury delayed his return further.

Earlier on Wednesday, Longmire said Mills had trained at "110 per cent" but said hadn't made a decision on whether to recall the skipper.

A couple of hours later, Mills was ruled out.

Mills was previously picked for the 2016 grand final loss to the Western Bulldogs after overcoming a hamstring injury suffered in the first week of that year's finals.

Longmire knows better than most how risking an injured player can pay off or backfire.

He lamented playing the injured Sam Reid in the 2022 decider as a "mistake", after the severely hindered big man struggled then had to be substituted out soon after halftime in the embarrassing loss to Geelong.

But in 2012, Ted Richards was picked off an ankle injury and successfully quelled Lance Franklin to help the Swans to victory.

There are no concerns over key forward Logan McDonald, who has overcome the rolled ankle suffered against the Power.

"Nah, he was good," Longmire said.

Former captain Stuart Maxfield will present the premiership cup if Sydney win the grand final, while former Brisbane coach Leigh Matthews would do so if the Lions prevail.
