Rockets center Nene left Sunday's game in the first half with a pulled groin muscle and was ruled out for the game.
Nene, 34, scored two early buckets, including one on a steal that he brought the length of the floor, but played just two minutes before heading to the locker room.
Starting power forward Ryan Anderson returned to the court to replace Nene. Third-team center Montrezl Harrell is also available.
