Boston center Shaquille O’Neal is listed as doubtful for Tuesday’s Game 2 of the Celtics’ Eastern Conference semifinal series against the Miami Heat.
Celtics coach Doc Rivers says O’Neal may be "likely" to play in Game 3 at Boston on Saturday.
O’Neal has missed much of the past three months with calf problems.
Meanwhile, Heat coach Erik Spoelstra says forward Udonis Haslem will remain out for Game 2. Haslem has not played since Nov. 20 with a ruptured ligament in his left foot.
