Phoenix Suns small forward T.J. Warren left Friday’s game against the New York Knicks with a head injury.

On a play in transition with 2:10 left in the first quarter, Warren received a pass from Devin Booker and when attacking the basket, took a bump off Knicks big man Enes Kanter. Kanter went straight up as Warren collided with him.

The Suns announced Warren would not return due to a headache.

The Knicks said Kanter had a laceration under his chin from the collision.
