Harden made the remarks after Houston's 111-106 loss to the Los Angeles Lakers on Thursday, calling Foster "rude and arrogant." The guard fouled out of the game in the fourth quarter.
He also suggested that Foster has a personal vendetta against him.
"It's lingering," Harden said. "It has to be looked at. For sure it's personal. For sure. I don't think he should be able to officiate our games anymore, honestly."
