(USA TODAY/Jeff Zillgitt) — The NBA on Wednesday fined Boston Celtics guard Isaiah Thomas $25,000 for "directing inappropriate language toward a fan," during Game 3 in Washington.

NBA executive vice president of basketball operations Kiki VanDeWeghe made the announcement in a news release.

The series is tied 2-2 with Game 5 on Wednesday night in Boston.
