Sports Illustrated's Chris Mannix reported the news Thursday:
In the fourth quarter, Price was guarding Rivers, who penetrated to the basket. As Rivers attempted a shot, Price hit him in the head with a forearm. Referees whistled Price for a flagrant foul and ejected him from the game.
You can view the offending play below.
Pro Basketball Talk's Kurt Helin felt the NBA made the right decision:
Doc Rivers, Austin's father, however, wasn't sure if the foul warranted any sort of suspension, per Ben Bolch of the Los Angeles Times:
Through eight games this year, Price is averaging 4.3 points, 1.9 rebounds and 4.4 assists in 21 minutes a night.
He's set to miss Friday night's game against the San Antonio Spurs.
