The NBA has fined three coaches of $45,000 each for publicly criticising referees during the basketball playoffs.
Houston's Rick Adelman, Portland's Nate McMillan and Boston's Doc Rivers all received the fines.
Adelman and McMillan are facing each other in a first-round series that Houston leads 3-1.
Both coaches were fined for comments after Houston wins.
Rivers was fined for comments made after a 121-118 loss to Chicago in two overtimes that tied their series at 2 all.
