LaVar Ball -- the father of basketball stars Lonzo, LiAngelo and LaMelo Ball -- had his foot amputated after suffering a serious medical issue, TMZ Sports has learned.
We're told the Ball family patriarch underwent a recent procedure to have his right foot removed ... but despite it all, he is in great spirits and doing well.
LaVar made a name for himself with his grandiose plans for his sons -- he created the Big Baller Brand, which developed signature shoes for all three hoopers.
