After Friday's 97-86 loss to the Cavs, Spurs guard Tony Parker said he wanted his big man back, who was out because of quad tendonosis.
"I wanted Timmy to play," Parker said. "I was worried in a game like that everybody would run out of gas because the last two games we spent so much energy in a back-to-back, especially coming off a long road trip. I was just scared we didn't have enough in the tank, and it showed tonight."
Duncan hasn't played since being unable to shake a stiff knee just before Tuesday's victory over Dallas. He showed no signs of pain while shooting jumpers at a morning workout, and doctors gave the green light to Duncan's wishes to return Friday.
Spurs coach Gregg Popovich wasn't on board, though. Flatly saying that Duncan is "too important to us," Popovich chose to rest him another night and said his big man would probably return Sunday at Portland or Monday at the Los Angeles Clippers.
Duncan leads the Spurs with 20.7 points and 10.7 rebounds per game.
