Adebayo rejoined the lineup for Game 4 of the NBA Finals against the Los Angeles Lakers on Tuesday night, with the Heat making that determination more than hour before game time. Dragic was ruled out around the same time after he tried to test his torn left plantar fascia in a warm-up session.
Adebayo had 15 points and seven rebounds over 33 minutes in his first action since Game 1, but the Heat lost 102-96 to fall into a 3-1 hole.
"Physically still not a hundred percent, but I was moving well and getting back to a hundred percent,'' Adebayo said.
Miami had seen steady improvement from one day to the next, and there were multiple indicators that Adebayo could be ready for Game 4 -- such as him taking the court before Game 3 on Sunday for some light shooting, then the decision by the team on Monday to upgrade his status from doubtful to questionable.
"He passed all the protocols with his mobility and strength, and I thought he was great considering he hasn't played in a week or hasn't really done anything other than rehab,'' Heat coach Erik Spoelstra said. "But he's the heart and soul of who we are. So it was just great to have him back out there, and I don't have to deal with him trying to stare a hole through me anymore.''
Before these finals, Adebayo had missed only one game for injury; a sprained ankle cost him an appearance in his rookie season, when he also sat once for personal reasons and 11 times by coach's decision. He played in all 82 Heat games last season and their first 72 of this campaign -- sitting out the 73rd and final regular-season contest for rest because it was largely meaningless to Miami in terms of standings or playoff matchup.
"I don't miss games,'' Adebayo said Monday. "That's not me. That's not how I'm built. I want to play. I've always been like that. I've always got the thrill of just putting on that uniform and going out there and playing.''
He has been playing through a shoulder issue for some of this postseason run, but a neck strain has been the concern during the Finals.
Dragic hasn't played since tearing the plantar fascia in the first half of Game 1. He did some shooting before Tuesday's contest, but his workout ended abruptly after he attempted to move laterally while guarding Heat assistant coach Chris Quinn.
Averaging 16.2 points off the bench, Dragic was Miami's second-leading scorer in the regular season behind Jimmy Butler. Adebayo averaged 15.9 points and 10.2 rebounds in his first All-Star season.
In the playoffs, both raised their numbers: Dragic became the starting point guard, and he has averaged 19.9 points, while Adebayo entered Tuesday averaging 17.8 points and 10.9 rebounds.
