Adebayo is officially listed as questionable for Tuesday’s contest because of a neck strain that forced the All-Star center to miss Games 2 and 3.
The Heat also could be bolstered by the return of point guard Goran Dragic, who will be a game-time decision Tuesday, a source told Wojnarowski.
Dragic is dealing with a foot injury and also has missed the last two games. He is officially listed as doubtful for Game 4.
Adebayo said Monday that he was “trying to get back as quickly as possible,” but noted that the Heat are “trying to make sure I’m safe and I’m ready to play.”
Meyers Leonard has started at center in each of the past two games for Miami, which faces a 2-1 series deficit. Kelly Olynyk — another 7-footer — has scored 41 points off the bench in the past two contests.
Adebayo told reporters Monday that he doesn’t like to miss games, saying “that’s not me,” but also said he understands the caution being taken by the Heat’s medical staff.
“To be in the Finals and the medical staff is telling me I can’t play … it sucks, but I understand,” he said.
Adebayo also has been dealing with a shoulder injury that flared up during the Eastern Conference finals against the Boston Celtics.
