The NBA has fined Chicago Bulls guard Rajon Rondo $25,000 for attempting to trip Boston Celtics forward Jae Crowder from the bench in Game 3 of their first-round series.
The league announced the fine hours before Game 4 tips off on Sunday.
The incident happened with 31.1 seconds remaining in the first quarter on Friday.
Crowder jawed at the Bulls' bench after hitting a jumper and Rondo - sidelined by a broken right thumb - extended his leg as Crowder walked by.
The top-seeded Celtics went on to win 104-87 after dropping the first two games at home. Rondo said afterward he was simply stretching his leg.
