Cavaliers forward Mike Miller has a concussion and will miss Friday's game against the Raptors, the team said.

Miller's status going forward will depend on how he performs in the series of tests he'll undergo as a part of the league's concussion protocol. The Cavaliers will return to New York on Saturday and stay there through the weekend as they face the Nets in Brooklyn on Monday.

"I very much understand what the process is," Blatt said before the Cavs played the Raptors. "Now what and how quickly he recovers, that's a part of the process too. And we will adhere to the NBA policy and certainly wait for Mike to get well."

Miller left the Cavaliers' 90-87 victory over the Knicks on Thursday night with 2:28 remaining. Blatt could not provide a potential timeline for when Miller would be able to return to the lineup.

He was inadvertently struck in the head by Carmelo Anthony as Miller was called for an offensive foul for sticking out his leg to draw contact with Anthony as he missed his only shot of the game with 2:52 remaining and the Cavs up 88-87.

Miller was scoreless in 11 minutes off the bench.
