According to Fox Footy, 2021 interim coach and long-term assistant, Robert Harvey, has departed the Holden Centre after a decade of service, with a return to Princes Park under his former mentor, Ross Lyon, appearing likely.
Harvey, 50, guided the Pies across their final nine-games this season for a record of two-wins and seven-losses.
The St Kilda legend had previously worked under Lyon during an assistant stint at Moorabbin, with the pair first joining forces at the Blues following the dual Brownlow medallist's retirement in 2008.
In a report filed by Tom Morris and Ben Cotton on Tuesday, it was also suggested that another of Nathan Buckley's former assistants in Brenton Sanderson could join Harvey in heading for the exits, with a contract extension unlikely for the 47-year-old.
Sanderson has called Collingwood home for the past seven seasons following his sacking as Adelaide's head coach in 2014.
Although it is yet to be officially announced, McRae is seen as a certainty to fill Buckley's void on a permanent basis, with an announcement expected by the end of Wednesday.
However, Morris tweeted on Tuesday morning that the 47-year-old had already toured his new facilities and terms between both parties had all but been agreed upon.

Having honed his craft at the Lions, Tigers and Hawks, McRae is seen as an ideal candidate by many to help steer Collingwood's rebuild.
Speaking on SEN, McRae's premiership teammate, Justin Leppitsch, claimed that if his previous posts had proven anything, the South Australian had the capability to get the Pies humming from next season.
“He was always bringing the team together,” Leppitsch told Gerard Whateley on Wednesday morning.
“There wouldn’t be a person who doesn’t like ‘Fly’. He’s that sort of person, he gels people together.
“That’s his strength, that’s his one-wood, is the fact that he’s respectful of everybody. He understands the big picture, he knows he can’t do this job on his own.
“He’s lived through almost every scenario in footy from the high of the high to the low of the low.”
Leppitsch and McRae had also spent time together during their tenures at Tigerland, with the former stating that his friend had a thirst to improve whenever possible.
“He’s got that well rounded experience. He worked at the Melbourne Storm as well so he seen a lot of different sports in what he’s done,” Leppitsch continued.
“It’s not bad, is it? That’s why it’s a really mature appointment from Collingwood going down this path.
“It’s almost saying, ‘What do we need at our footy club?’. They know what they need, they went out seeking it and they’ll put the parts around that.
“That’s what long term success is about.”
As mentioned, an official statement from Collingwood is expected to be made before the close of business on Wednesday.
