Sullinger out indefinitely with foot stress "reaction" | Celtics Insider | | Boston Herald
There’s nothing glummer than a glum-looking big man with his foot in a therapeutic walking boot. But such is the lot of Jared Sullinger, who received the news today that he will be out indefinitely following a trip to have an X-ray taken of his left foot. The diagnosis was a stress reaction to the fourth metatarsal – an injury that Sullinger thinks occurred during the Celtics' Feb. 11 win over Atlanta.
Sullinger's going to be "out awhile," Stevens said. Stress reaction in his foot. "Not good news," said Stevens, "that's for sure."— Jay King (@ByJayKing) February 19, 2015
Sullinger has stress reaction to fourth metatarsal on left foot. Out indefinitely.— Mark Murphy (@Murf56) February 19, 2015
Sullinger believed pain in his foot was just a sprain of some sorts. Hoped it'd pass over break. Practiced yesterday, and it became worse.— Marc D'Amico (@Marc_DAmico) February 19, 2015
The good news is, Kelly Olynyk was back on the practice floor. He's likely out for tomorrow night (unless he went through a full practice today), but his return is imminent. Sullinger is a different story. He won't need surgery, but stress reactions are no joke. For example, Bradley Beal has missed large chunks of time over the last three seasons due to a similar problem. Beal has an issue with his fibula where as the 260-pound Sullinger has problem is in his foot.
