Collingwood coach Nathan Buckley has confirmed midfielder Brayden Sier hasn't been suspended for lying to the club, but will be fined $5000 and must do some community work every week until season's end.

Sier was spotted playing social basketball on Monday night, and told the club he was just shooting around during breaks of a game.

However, it was later revealed Sier was playing in the game under the alias 'Phill Inn', despite trying to recover from a calf injury.

Following Collingwood's big win over Adelaide on Saturday afternoon, Buckley confirmed Sier's punishment.

"We've spoken to Brayden and he's spoken to the group (about) what is quite a marginal action (that) has got a lot of coverage," Buckley told reporters.

"He's been sanctioned and he understands what he did was not a great decision.

"He's been fined $5000 and he's doing some community work, one night a week, each week for the rest of this year.

"We'll put our support behind him now and he's still part of our campaign and needs to get back on track, train well, play well in the VFL next week and continue to push to be a positive impact on the rest of our 2019 campaign."

Buckley did say however it wouldn't be season over for Sier in terms of a recall to the senior side, suggesting he would be available for selection for September action.

"Brayden's got a bit of work to make up in a very short space of time, but we don't know where the twists and turns of the next hopefully five weeks, six weeks for us, we don't know where that's going to take us, so we're not going to leave anyone on the side of the road," Buckley said.

"We need all hands-on deck and Brayden will be part of that.

"We made the decision that we think is the right one for Brayden, for now and for the future to teach him and educate him.

"He's a young player and it's also the right decision to maintain integrity around our expectations at the football club.

"We have some guys on the injury list, but it's not bad as some people think either."
