Brooklyn Nets guard Kyrie Irving was fined $50,000 by the NBA on Tuesday for directing obscene gestures and profane language at spectators, the league announced.
The league fined Irving for words and gestures made during Brooklyn's 115-114 loss at Boston on Sunday.
The news came on the same day Nets coach Steve Nash said that guard Ben Simmons has taken part in a full contact workout as he fights to return from a back injury.
The Australian star, obtained in a trade that sent James Harden to the Philadelphia 76ers, has not played since last May.
And while Nash ruled out Simmons playing in game two of the Nets' first-round best-of-seven playoff series against Boston on Wednesday, he was non-committal about later games.
Nash said Simmons took part in a four-on-four game situation workout on Monday and has also been working on his shot form with shooting instructor Kyle Korver.
