It was a rare moment of humility from LaVar, who has been hyping up a mano-a-mano matchup with the GOAT for years.
But, at the Ball fam's turkey giveaway in South Central L.A. on Tuesday, LaVar told us straight-up -- it's not happening.
"Realistically, neither one of us is gonna do this," LaVar told TMZ Sports. "We over 50!"
Don't get it twisted -- LaVar joked both guys would be down if it came with a crazy price tag of $200 MILLION and at a crazy location like the Empire State Building ... but in reality, the only one getting the W is father time.
But, now that LaVar's pulled off the game, we asked if he's chopped it up with his son's new boss and maybe smoked a cigar or 50 together.
By the way ... MJ will def consider this video a victory -- he's an insane competitor and would never say he's too old for anything.
There's more ... we also spoke with LaVar about the Balls unloading a semi-truck-worth of supplies for the Thanksgiving holiday ... and why it's so important for the family to give back to the community.
