Coach Doug Collins did not attend the 76ers' practice Sunday because of a sinus infection. The Sixers listed Collins as day-to-day.
The 61-year-old coach left in the third quarter of Saturday's 97-80 victory over the New York Knicks to be treated for the infection.
Collins was examined by team internist Daniel Lazowick after the game. He was replaced in the game by associate head coach Michael Curry, who ran Sunday's practice.
The Sixers coach has left the bench before because of health issues. Last season, he left during a game at Detroit because of dizziness. In 2010, Collins missed a pair of games because of vertigo. At halftime of a regular-season game against Indianapolis that season, Collins remained in the locker room with recurring symptoms.
