NEW YORK (WFAN/AP) — Deron Williams’ season is over.

The two-time All Star will have bone fragments and scar tissue removed from his right wrist in an operation on Friday afternoon, coach Avery Johnson said.

Johnson said power forward Kris Humphries, the league’s fifth leading rebounder (10.4), is going to miss the last four games because of ankle and heel injuries in his right foot.

Williams strained his right wrist in January and the Nets were aware of it when they acquired him from the Utah Jazz on Feb. 23 in a multi-player deal. However, an MRI on Wednesday showed the injury worsened compared to what an MRI showed when the Nets made the trade.

“I think this was something that developed,” Johnson said. “I’m just glad we found it and he’s going to have the procedure done and we can get it behind us and, hopefully, he won’t have to deal with this at another point in his career.”

The news comes just days after New Jersey unveiled a new billboard in Times Square, touting “Deron Williams & The Nets Bound For Brooklyn.”

After draining Tuesday night’s game-winning shot, Williams admitted he could skip the rest of the season with his team out of playoff contention.

“There’s a possibility this is the last (game),” he said.

He has averaged 15 points and 12.8 assists in a dozen games with the Nets.

“We clearly know where we are with this team,” Johnson said. “Deron is definitely driving the car and when he’s not driving it we’re a different team.”

Is this a good move by NJ with the Nets out of the playoff picture? Let us know in the comments below…
