Bradley Beal will sit out the remainder of the NBA season to undergo wrist surgery.

Washington Wizards guard Beal, who can become a free agent at the end of the season, has sat out the past four games and will not return after deciding to go under the knife to repair a torn scapholunate ligament of his left wrist. 

"Despite the last 10 days of getting intensive treatment and rehab on my wrist, it became clear that I would not be able to compete to my standards or to the level that our team and our fans deserve," said Beal. 

"I'm disappointed to have my season end this way, but we all agreed that this was the best decision. I look forward to coming back at 100 per cent and continuing to lead this team as we work together to build toward the future." 

The All-Star is eligible for a five-year $245million extension with the Wizards in the close season. He also has a $36.4m player option for next term. 

Beal had been heavily linked to a trade before Thursday's deadline, but that now appears unlikely. 

He was rumoured to be a target for Philadelphia 76ers as they continue to look to offload Ben Simmons, while the Atlanta Hawks and New York Knicks had also been touted as potential trade candidates. 

Beal was averaging 23.2 points, 6.6 assists and 4.7 rebounds.
