Per ESPN's Brian Windhorst, the NBA will review and determine any potential punishment for Oubre for wearing a black jacket with "f--k you" stitched into the back.
In 2005, the NBA instituted a mandatory dress code that requires players to wear business casual attire for team or league business events.
Oubre has had several on-court incidents that have resulted in fines throughout his career. The 21-year-old was fined $25,000 for kicking a ball into the stands last April during a playoff game against the Atlanta Hawks.
A first-round pick in 2015, Oubre has evolved into a prominent role with the Wizards over the past three seasons. He has already started more games this season (six) than he did during the entire 2016-17 season (five) and is averaging a career-high 11 points and 5.6 rebounds per game.
