Butler played just 12 minutes Sunday against the New York Knicks and didn’t see the second half after scoring three points and grabbing a rebound. After the game, Butler said his back felt tight prior to the contest and it got progressively worse; he said he simply couldn’t play after halftime.
Clippers coach Vinny Del Negro said Billups' back was tight after Sunday's game and that he would monitor it Monday with the training staff. Billups was a late scratch before tipoff.
The injuries are obviously a setback for a Clippers team that was only able to play two games with a completely healthy roster after having Chris Paul, Blake Griffin, Jamal Crawford and Billups return from injuries last week.
Butler and Billups will be reevaluated when the Clippers return to Los Angeles Tuesday morning and are officially listed as day-to-day.
