Washington Wizards star Trae Young left their matchup with the Golden State Warriors early on Monday night due to a leg injury.

Young collided with Warriors guard Will Richard while trying to get through a screen midway through the third quarter at Capital One Arena, and was called for an offensive foul after knocking Richard down. Young immediately started limping as officials called the foul, clearly shaken up.

He remained on the floor for one more play, still in noticeable pain, before he was finally taken out of the game. He limped off the court, went back to the locker room and did not return.

The Wizards quickly ruled Young out with what they called a right quad contusion. Further specifics of his injury are not yet known.

Young finished the night with a team-high 21 points after he went 7-of-10 from the field. He had five assists and two rebounds, too. Monday night was just Young’s fourth game with the Wizards. He made his debut with the team earlier this month after being dealt there from the Atlanta Hawks ahead of the deadline.
