LeBron James was suspended for the first time in his 19-year NBA career.

James was suspended during a paid game “for recklessly hitting” Detroit Pistons center Isaiah Stewart during an on-court altercation, the NBA announced Monday. In Sunday’s game of the Lakers against the Ditroit Pistons, James punched Stewart in the face.

Stewart was suspended two games without pay “for escalating an on-court altercation by repeatedly and aggressively pursuing Los Angeles Lakers forward LeBron James in an unsportsmanlike manner.”

The league says James will serve his suspension Tuesday when the Lakers visit the New York Knicks at Madison Square Garden.
