He will be re-evaluated Thursday.
Nene stayed on the court for several minutes after Jazz forward Carlos Boozer banged his left leg into Nene's knee. He was helped off the court and into the locker room leaning on trainer Jim Gillen.
"I don't know how severe his injury is, but if he doesn't play we just have to play without him," Nuggets acting coach Adrian Dantley said. "Utah, they went without two players. We just have to play without him."
Nene was having another quiet game, with two points and one rebound but four assists when he went out.
"It looks like when he went out they picked themselves up and it seems like they were a lot stronger," Jazz coach Jerry Sloan said. "That is what happens a lot of times when you have guys who have the chance to play and they try to make up the difference."
