Washington Capitals defenseman John Carlson won't play Monday in the club's round-robin opener against the Tampa Bay Lightning, the Capitals announced.

Carlson exited during the third period of Washington's exhibition game against the Carolina Hurricanes last week and did not return. He skated with the team over the weekend, but the nature of his injury is unknown.

The Norris Trophy candidate enjoyed a career campaign in 2019-20, leading all defensemen with 60 assists and 75 points through 69 games. His 15 goals matched a personal best.
