Miller was injured in the fourth quarter of the Cavaliers' 90-87 win over the New York Knicks on Thursday when he was accidentally hit in the head by Knicks forward Carmelo Anthony. Miller played 11 minutes in the game and did not score.
The Cavaliers placed Miller in the NBA's concussion protocol program and said they would update his status when appropriate.
According to the league’s protocol, each player with a head injury will undergo baseline testing and won’t return to action until a neurologist is consulted, clearing the player to resume basketball activities.
Miller is averaging 1.5 points and 2.1 rebounds in 12 minutes per game this season.
The Cavaliers (10-7) have won five in a row and next take on the Toronto Raptors, who have the best record in the Eastern Conference, on Friday.
