Collingwood are set to be boosted by the return of injured trio Adam Treloar, Tyson Goldsack and Jeremy Howe for Saturday night's qualifying final against West Coast at Optus Stadium.

Reported by The Herald Sun's Sam Edmund on Twitter, reports circulated on Thursday morning that there were three significant bouts of cheers in the Magpies huddle at their final training session.

Collingwood unveiled this teaser video on their Twitter account later in the afternoon, indicating positive new at the selection table.

Treloar has been sidelined since the Pies' round 14 clash against Carlton where he suffered a horror double-hamstring injury that required surgery.

Goldsack has not played a senior game in 2018 after rupturing his ACL during the pre-season, but has appeared in the last couple of VFL outings.

Howe has missed the past four games following complications to a corked thigh.
