SYDNEY Swans coach John Longmire has marvelled at dual Brownlow medallist Adam Goodes' physical resilience and ability to race to the 300-game milestone.

Goodes, 31, will become the 64th player in the game's history to play 300 games on Friday night in the Swans' semi final against Hawthorn, and just the fourth indigenous player to rack up the triple ton.  

He is also the fastest player to reach the milestone, achieving it in 12 years and 172 days since his round one debut in 1999 against Port Adelaide, which eclipses the previous record held by former Adelaide captain Mark Ricciuto.  

Longmire said Goodes had requested to keep his milestone "low key" this week and there hadn't been much talk about it among the players.

Even so, he says he continues to be surprised by Goodes' evolution as a player, which has seen him improve his leadership skills and ability to do important things at crucial stages of games this season.

"He's gotten to 300 in the same time I probably got to 200," he said, after the team trained on Thursday at the MCG.

"He's an incredible athlete, he's just under 100 kg and 193cm and he's the quickest player on our list, and that includes Gary Rohan and Ben McGlynn and all the other blokes we've got, Lewis Jetta [as well].

"He's a real professional and that's how he's been able to get there that quick. He does everything he possibly can and he's mentally strong; he's able to play with injuries he's had over this period of time, and still perform well.

"He doesn't use it as an excuse; he gets out there and does his best for the team every week."

Youngsters Dan Hannebery and Gary Rohan both trained in Melbourne and are expected to line up against Hawthorn.

Hannebery dislocated his shoulder against St Kilda last Saturday night while Rohan pulled up with a sore knee from the elimination final win.

Longmire said both were expected to take their place in the side, as will Jarrad McVeigh, who will join his teammates in Melbourne later on Thursday.

"[Hannebery] has had a big week in the coaches' offices telling us he's going to play," he said.

"He's been confident and from the moment the game finished last week he's been telling everyone he'd be right.

"In the end we had to tell him to jump out of the office and give us a rest.

"He's fine, he's a pretty tough kid and he was always going to back himself in."

Longmire admitted it was a risk to play Hannebery, after his shoulder completely popped out last week and had to reset by the club's doctor.

However, he said a similar injury to his other shoulder late last year had proven the 20-year-old could play through pain.

The Swans' scouts had their eyes on the MCG earlier on Thursday as the Hawks went through their paces, with Lance Franklin restricted to minimal training as a result of the bone bruising he sustained last Friday night against Geelong.

The Hawks are expected to name Franklin and make a final decision on his availability ahead of the game.

Longmire said the Swans were unsure whether he'd play, but were unconcerned as football was "less about the mind games and more about hoping your good players play".

"It's hard enough worrying about our team let alone what Alastair Clarkson is going to do with Hawthorn," he said.

"We prepared earlier in the week as we normally do, we looked at Hawthorn with Buddy and without Buddy, but most importantly for us, we've got to look at what we do.

"We've also got to look at Hawthorn's other players and structures and systems they normally play with.

"We'll have to wait until the teams are announced and even then, we won't really know until 90 minutes before the game."

Longmire also said the Swans held no concerns over playing at the MCG, where they have won just one game from their past 13 starts, which was in round 19, 2009, when they beat Richmond by 55 points.

He said the Swans were just happy to be playing finals, and the location was irrelevant.
