Incredibly, Jack Silvagni appears to be nearing a move to Collingwood as a free agent on a four-year deal.
Three generations of Blue in his veins, Carlton through and through, on the verge of signing a long-term contract with their biggest rivals.
Magpies coach Craig McRae confirmed on Wednesday he'd met with Silvagni to discuss the potential move.

"Yeah I did. And I'm confident to say we'll keep exploring what the best version of us looks like, and when there's free agents available we'll keep exploring those things," McRae said, before being asked about the club's chances of landing the backman.
"Justin Leppitsch and Charlie Gardiner do those things.
"I just met with a young man and we had a first date to see if we liked each other.
"Yeah, I could go on a second date with Jack."
One can make a strong case that, if it happens, it's among the most shocking moves in modern footy history.
Of course, there have been other stunning player switches.
Gary Ablett Jr. was about as Geelong as they come, having grown up around the club while his father dominated the league, before doing the same himself.
He left to join the Suns, but money and lifestyle were major factors there, and he was signing with an expansion club with no history or rivalry with Geelong.
When the Swans swooped in under everyone's noses to poach Lance Franklin as a free agent in 2013, the football world was blindsided, but mainly because the expectation was he'd join GWS.
Buddy's nine-year, $10 million deal was also unprecedented at the time and no doubt helped in getting the deal done.
While both Ablett and Franklin were more influential players than Silvagni, the 27-year-old's connection to Carlton, and the Blues' rivalry with the Pies, would make this one particularly seismic.
Josh Kennedy's family history was closely woven into that of the Hawks when he departed to Sydney, but the rising midfielder had played just 13 senior games and couldn't see a way into Hawthorn's team.
Silvagni, on the other hand, has played 128 times for Carlton, is in the prime of his career and has established himself as key cog in their backline.
Additionally, reports claim that Collingwood's offer to the defender, while slightly more lucrative, doesn't exactly blow Carlton's out of the water.
All hope isn't lost for the Blues yet, though, with incoming CEO Graham Wright reportedly placing Silvagni's retention at the top of his to-do list.
With frustration building among long-suffering Bluebaggers following another disappointing season, expect it to boil over if Silvagni runs out in black and white next season.
