Williams (inflammation in both ankles) sat out Monday's victory in Indiana and will miss Wednesday night's game against the Nuggets.
Williams was averaging just 13.7 points, 5.7 assists and 4.0 turnovers and shooting 38.7 percent from the field in his final six games prior to being shelved.
Nets interim coach P.J. Carlesimo said injuries have played the biggest role in D-Will's season-long struggles.
"I think (that's) a huge, huge part of it," Carlesimo told Michael Kay on ESPN New York 98.7 FM. "He's a competitor and he plays, he plays hurt. ... The combination of the Olympics, coming back from the Olympics, and he'll be the first to admit it, he felt he came back and got back into it too quickly.
"In retrospect, I think he would admit he probably should've taken a couple weeks off, tried to shut it down and tried to re-energize him body. And I think it's inhibited him all year."
Carlesimo also mentioned that Williams, who has dealt with a sprained right shooting wrist along with his ankle ailments, is probably playing too many minutes. The 28-year-old is averaging 36.5 minutes per game.
"Maybe we need to manage his minutes a little better than we have," Carlesimo said. "Hopefully the (rest) is gonna make a big difference. Hopefully it'll reinvigorate him."
Carlesimo also addressed some other things:
On his team not being more vocal in light of its recent struggles: "I would like some more emotion some nights, but that's not something you can manufacture. ... Our biggest problem has been our schedule and us not shooting the ball well. That's been hurting us."
On possibly making a trade: "Billy's got a good handle on our roster. He knows what we need ... so I think we're gonna be listening, but I don't think we necessarily have to make a trade."
On his love of the Yankees: "I grew up a Yankee fan before the Mets were even in existence, and I've stayed a Yankee fan my whole life."
