Gordon Hayward is currently in quarantine after re-entering the NBA bubble on Monday night.
Hayward sprained his right ankle in the first round against the Sixers.
Hayward was initially projected to be out 4-6 weeks with the injury.
“I don’t know when the quarantine period will end. I think they will determine it through a set of doctors and all that stuff, how long that is. But my understanding is that I know he’s back, and I haven’t seen him because he’s been in a room," said Brad Stevens following the Celtics' game 5 win on Monday.
The Celtics currently lead the Raptors 3-2 in the series.
