Howard was to miss Tuesday night's home game against the Miami Heat over the incident in the fourth quarter of the Rockets' 123-122 loss to the Washington Wizards on Saturday.
He made contact and struck the arm of one of the officials.
Howard scored 20 points and grabbed seven rebounds in the game but was ejected for the second straight contest after tangling with Wizards center Nene.
They shoved each other and Referee Mitchell Ervin stretched out an arm in warning. Howard, who leads the league with 12 technical fouls this season, pushed Ervin's arm down and walked away, later apologizing for making contact with the official.
After the game, Bickerstaff blasted NBA officials, saying they routinely fail to call "dirty" play against Howard.
Bickerstaff said Rockets executives, including owner Leslie Alexander and general manager Daryl Morey had brought up the issue with the league office "tons."
Bickerstaff also criticized the overall officiating of Saturday's contest.
"We don't like to blame referees," Bickerstaff said. "Tonight, there were too many calls that were critical (that were) missed and they went the other way."
