Collingwood coach Nathan Buckley says star midfielder Dane Swan is 'remorseful and embarrassed' after he was suspended for two weeks for breaking club rules on the consumption of alcohol.
Buckley revealed that a blanket ban on alcohol - instigated by the players - had come about in the wake of the club's 47-point loss to Hawthorn at the MCG over two weeks ago.
When the 27-year-old arrived at training on Monday morning, several players and staff members were aware Swan was notably subdued, leading to questioning which he revealed he had been drinking on Sunday night.
The Magpies acted swiftly, ruling the 2011 Brownlow Medallist out of matches against Sydney and North Melbourne in the next fortnight despite the significance of them in relation to the club's top-four hopes.
"Swanny has failed to meet the expectations of the (playing) group," Buckley told reporters on Wednesday.
"Dane has accepted that he was drinking when he shouldn't have been. It was there for all to see (regarding) the state that he had come to the club in (on Monday). It was pretty clear he was under the weather.
"He has got his tail between his legs. He made a poor decision that he is quite remorseful and embarrassed about."
Buckley, who said he was 'extremely disappointed' with Swan's actions, said the decision to sideline the midfielder - who has averaged 36 disposals in 2012 - was not difficult, adding that the tough stance was essential in the long term.
"Our duty as a club, to our members and supporters, is to give ourselves the best chance of success in the short, medium and long term," he said.
"We can sweep this under the carpet and it might help the short term but I personally believe that compromises the medium to long term chances of the footy club to succeed.
"If you are not practising success day by day and if you are not making decisions based on what success looks like, day by day, then you are practising failure."
Swan will not play any football over the next week, although he is a chance to feature for Collingwood's VFL side against Casey Scorpions at Victoria Park on August 18.
Of more immediate concern for the Buckley's side is a battle with Sydney at ANZ Stadium on Saturday night, a side they have beaten 10 times in a row.
"They are the ladder leaders and they are in great shape. They have won the last nine in a row. It's an awesome, awesome challenge for us.
"When you have a positive record on a side, I think it has an impact. You'd like to think (it does)."
Alan Didak is in the selection mix after impressing in the VFL last week, while Chris Tarrant is also a chance to return after withdrawing from Saturday's match against St Kilda with back spasms.
