Sullinger said he twisted his ankle when he stepped on an opponent's foot chasing a rebound during Saturday's loss in Washington. He sat out Monday's practice and was only expected to be a limited participant in Tuesday's session.
Asked before Tuesday's practice if he planned to play on Wednesday, Sullinger said, "I don’t know. That’s a good question, great question."
Even Celtics coach Brad Stevens seemed uncertain on Sullinger's status.
"I’ve heard mixed reports on [Sullinger's health]," Stevens said. "I’ve heard that he’s sore again this morning. He did get taped. I don’t know how much he’s going to do. I don’t know if he’ll go live or not. I think he’ll at least do some shooting."
Stevens said Sullinger's status will hinge on his progress and whether he's cleared by the training staff.
For his part, Sullinger said he was eager to practice and didn't like being stuck on the sidelines. He sounded optimistic about his chances to play while noting, "I’ve played through so many injuries before, health is not really an issue to me."
The Celtics are hoping to have Marcus Thornton available for Wednesday's game. The reserve guard has missed the past seven games due to a left calf strain. He participated in most of Monday's practice and was hopeful Tuesday's session would put him in position to resume game action.
"We’ll see how he feels after practice," Stevens said.
Thornton said he tightened up a bit at times Monday, but felt good while participating in live action.
"We'll see how this practice goes and hopefully I can [play on Wednesday]," Thornton said. "I hate sitting out. I'm tired of sitting out."
