The team said he is out indefinitely.
He checked out of the game with 1:43 remaining in the quarter and had to be helped off the court to the Suns’ locker room, finishing with one rebound and one missed shot in two minutes of play.
The five-year veteran came into the Finals averaging 4.8 points and 2.6 rebounds in 11.1 minutes per game during the Suns’ postseason run.
Craig has been a regular part of the playing rotation, but Kaminsky hasn’t seen much time in the postseason.
