Drake has been warned for "the use of bad language" after his heated exchange with Cleveland's Kendrick Perkins during Game 1 of the Eastern Conference Semifinals, according to ESPN.
Kiki Vandeweghe, the NBA's executive vice president of basketball operations, talked to Raptors president Masai Ujiri about the issue, reports ESPN.
The Canadian rapper is a huge Raptors fan and is often seen sitting courtside at Toronto home games.
He first exchanged words with Perkins at halftime during Game 1 on Tuesday night.
After Cleveland took the 113-112 overtime win, the rapper and the Cavaliers' center argued again before being separated.
