As the Nets squared off against the defending champion Heat in Brooklyn Thursday night — after coach Jason Kidd saw his No. 5 jersey retired forever — Deron Williams sat on the bench in a suit jacket and slacks watching the festivities unfold in front of him.

Almost three weeks into training camp Williams still hasn’t fully practiced and he admitted Friday — after going through yet another limited workout — waiting for his sprained right ankle to be healthy enough to let him play has been frustrating.

“It’s just a process man” Williams said. “[Nets athletic trainer Tim Walsh] is taking it slow with me. It’s not about the first couple games … it’s about the end results.”

So far the end result has been Williams — who suffered the sprained ankle and a corresponding bone bruise during a workout in Utah in early September — spending the past three weeks mostly watching from the sidelines while his new teammates have gotten acclimated with one another. Williams initially said he would be ready to go when training camp began.

Now Williams said there was “no update” on his condition besides what has become the standard “day-to-day” and added he is hoping to be able to play when the Nets face the Cavaliers in Cleveland on Oct. 30 in the season opener now less than two weeks away.

”That’s my goal” Williams said. “Hopefully I can get out there before then. … I want to get a preseason game in too. Who knows … it’s literally day-to-day.

“It’s been a slow process. It’s been tough for me to adjust to. I’ve been [ticked off] at the training staff and doctors a lot but they’re smart and they know what they’re doing and they’re doing it for a reason so I’ve just got to accept that and kind of roll with it.”

With the Nets set to practice Saturday hold an open practice Sunday and practice again Tuesday Williams has a few more days to potentially get ready to play in at least one of the final two preseason games in Boston on Wednesday and Miami next Friday.
