Brad Stevens said that Gordon Hayward would rejoin the bubble soon, but is still some ways from returning to the court.
Hayward suffered a Grade 3 ankle sprain in game 1 of the Celtics' first round series against the Sixers.
"Rehab seems to be going OK. He feels a little bit better. ... I don't think his gait is perfect yet. Once his gait feels right and becomes perfect, he's probably on a quicker course to coming back.
"I think he'll rejoin us in the bubble at some point soon, but he still will be some time away when he does do that," said Stevens.
Hayward was initial ruled out for one month, with Monday representing two weeks since the initial diagnosis.
