Williams, who sat out Sunday's 98-92 loss to Washington, hopes that rest and treatment on the wrist will allow him to return for the club's final 12 games.
The decision to rest Williams was made during a meeting Saturday night between Williams, Nets coach Avery Johnson and general manager Billy King. Williams, who originally injured the wrist on Jan. 26 while playing for the Utah Jazz, considered continuing to play through the injury but decided that a brief rest was the better option.
"It's something that we know: rest -- not surgery -- is required," Johnson said. "We'll treat him. We'll rest him."
While sitting out the rest of the season was also a possibility, Williams decided against it because of his desire to play and help the Nets reach the playoffs. With 15 games remaining, the Nets are 6½ games behind eighth-seeded Indiana.
Williams said he was disappointed to be sidelined, but said it was "a strong possibility" he'd play again this season.
"I'm just getting a little rest and then re-evaluate it," Williams said. "Maybe a couple of more games. It's not really set in stone. I'll just see how it feels."
Doctors have told Williams and the Nets that he will not need surgery during the offseason and that three-to-six weeks of rest should heal the injury, which is officially being called a strained flexor tendon. Williams has been assured that he cannot further damage the wrist by playing.
Williams, who banged the wrist and reaggravated the injury in Friday's loss to Milwaukee, has averaged 16.2 points and 13.1 assists in eight games with the Nets. The wrist, however, has hampered his shooting ability, as he is hitting just 32 percent of his shots.
Johnson said in the short time Williams has played for New Jersey, he's seen what he can do at the point.
"I've seen enough, so I'm not overly disappointed," Johnson said. "We've seen flashes in certain situations."
Williams missed Sunday's game at Washington in hopes of returning Friday against Orlando.
