Three teams are tied for the one remaining playoff spot in the Western Conference.
The Utah Jazz are also tied for the eighth spot in the West.
The Nuggets won three straight and five of seven before falling to the Houston Rockets 106-103 on Friday.
“It’s frustrating but it’s not the end of the world,” said Nuggets center Marcus Camby, who had 23 points and nine rebounds. “The good thing about the NBA is you get to play again tomorrow. We play Portland tomorrow at home. That’s a big game because we’re still tied for eighth with them.
“We have two more games at home. We just have to take care of business. It’s not going to be easy. We’re playing tough opponents.”
The Nuggets led by as many as 15 against the Rockets, but they were outscored 36-21 in the third quarter.
“The third quarter was the difference,” Denver point guard Andre Miller said. “They started hitting open shots. The shots they missed in the first half, they made.”
After this game, Denver will close the regular season with games against Sacramento and San Antonio.
The Blazers are also coming off a loss. Portland had won four of five before falling to the Spurs 84-74 on Friday.
Blazers coach Maurice Cheeks realizes how crucial Saturday’s game at Denver will be.
“That will be a big game for us,” he said. “It would have been nice to win here.”
The Blazers will face the Spurs and Los Angeles Lakers in their final two games.
