Sydney  Swans coach John Longmire has expressed his disappointment in Michael Talia's arrest for drug possession, but vowed to continue to support his player.

Talia was stopped by police in Sydney's eastern suburbs early Sunday morning and has been charged with being in possession of a quantity of a prohibited substance, alleged to be cocaine.

He will appear in Waverley Local Court next month.

Talia has not played football at any level since the opening round of the season due to a foot injury suffered in the Swans' round one win over Collingwood.

Longmire said he stood by the club's decision to stand Talia down from training and club activities, but again reiterated that the 23-year-old would still get the support he needed from the Swans.

"Michael was injured, coming back, and getting ready to play again in a couple of weeks, so it's disappointing that he put himself in that situation," Longmire said on Tuesday.

"We've had a number of people speak to Michael and his family, particularly in the last 24-48 hours, and that will continue.

"He's got people at the football club that have spoken to him a number of times, whether it's to do with welfare or other services.

"People make mistakes, but my role as coach has been to re-focus the players on the playing of Carlton this week as quickly as we can, and that’s what we've talked about."
