Carlton coach Michael Voss has contacted former Port Adelaide player Tom Rockliff after he was spat at by a Blues supporter when leaving the MCG on Sunday afternoon.
Rockliff took to Twitter and said he was outside the ground with his four-year-old son when the Carlton fan spat at him.
"What a way to be let down," Rockliff wrote.
"Carlton supporters spitting at me when I am walking home with my son is not on.
"Passion is great but let's remember it's sport.
"I admit I was cheering harder than anyone at the 'G and pushed it - but there is a difference between cheering and being spat at."
Voss, who was an assistant coach at the Power when Rockliff was at the club between 2018 and 2021, contacted the retired midfielder after finding out about the incident on Sunday night.
"They've been really good and it's not a Carlton thing," Rockliff told News Corp.
"I spoke to Vossy. He called me (on Sunday) night. So it's not any single club supporter thing.
"It's just one of those things unfortunately that happens sometimes."
Carlton withstood the fast-finishing Power to win by three points after leading by 49 points at halftime.
