The surgery was performed by noted hand specialist Dr. Andrew Weiland and Nets team orthopedist Dr. Riley Williams III at the Hospital for Special Surgery in Manhattan.
It was Weiland who suggested Williams undergo a "fine-cut" MRI on Wednesday, which revealed that Williams would need surgery. Williams injury had previously been categorized as a strained right wrist. Doctors had initially told him he'd need 3-6 weeks for his injured wrist to fully heal and that he would not require surgery.
"The bony fragments and scar tissue taken from Deron's wrist today were interfering with this ability to flex his wrist," Dr. Williams said. "We expect a full recovery and a return to basketball-related activities in approximately 6-8 weeks."
According to a team press release, Williams' wrist "will be encased in a soft splint for two weeks, after which time he will begin rehabilitation. He is expected to be ready and healthy for the start of training camp."
Williams initially suffered the injury on Jan. 26 as a member of the Utah Jazz. Williams ended up playing 12 games with the Nets this season, averaging 15 points and 12.8 assists.
