Celtics' point guard Rajon Rondo suffered a sprained ankle in the team's loss to the Knicks on Friday night.

Rondo hurt the ankle in the third quarter and is expected to miss Sunday's game against the Nets with the mild sprain.

"I was yelling at him to get back on defense when he did it," joked coach Doc Rivers. "If he?s not 100 percent he won?t play."
