Isaiah Thomas (mouth) sustained a complete tooth fracture and two other subluxed/shifted teeth that required extensive oral surgery to stabilize.
To be clear, it sounds like he'll be ready for Game 4 on Sunday, but he may have to play through some discomfort. For the second time today, the Celtics confirmed Thomas does not have a broken jaw. Thomas is currently wearing a four-piece temporary bridge that cracked after being aggravated on Thursday. Because of that, the team gave him a replacement at halftime during Game 3. If his temporary bridge breaks again, the Celtics training staff is prepared to replace it at any time. He will need a permanent bridge at some point, which may occur in the offseason.
