The Houston Rockets were cruising to an easy 131-116 Game 5 win over the Warriors on Wednesday at Toyota Center when all hell broke loose.

Midway through the fourth quarter, Dillon Brooks was fouled by Moses Moody on a defensive rebound. As Pat Spencer walked away, he was bumped by Alperen Şengün.

Before Trayce Jackson-Davis could shove Şengün away, Spencer levied a headbutt on the Rockets’ NBA All-Star.

The referees reviewed the play and assessed offsetting technical fouls to Jackson-Davis and Şengün.

Spencer received a technical foul and was ejected for an “illegal headbutt” on Şengün.

The Rockets had built a massive lead and coach Steve Kerr pulled his starters midway through the third quarter. The Warriors’ reserves, led by Spencer, made the score closer than the game indicated.
