Jared Sullinger ruled out indefinitely

Boston Celtics star Jared Sullinger is out indefinitely after X-rays taken on Thursday revealed a stress reaction in his left foot.

Sullinger felt discomfort in his foot last week, and after removing himself from practice he underwent further tests.

"Jared is going to be out a while," Celtics coach Brad Stevens said, according to ESPN.

"Supposedly it happened in the Atlanta game and he was talking a little bit about it [Wednesday], with regard to feeling some discomfort and so he went through a little bit of practice, then pulled himself out. Ed took him to get the X-ray [Thursday], so that's not good news on the Jared front, that's for sure."

The Celtics star wore a protective boot as he watched practice on Friday, and although surgery is not planned, there is no timetable for his return.
