Beal, the Wizards' third-overall draft pick last year out of the University of Florida, will sit out the remainder of the campaign to recover from the injury to his right fibula.
The shooting guard has averaged 13.9 points, 2.4 rebounds and 3.8 assists in 56 games this season.
But he has also missed 18 games with various injuries, including a sprained left ankle, a sprained right wrist and a sore back.
Beal has connected on 91 three-pointers for the Wizards this season -- a club record for rookies.
