The Celtics came to this conclusion after Shaq failed to complete one simple sprint up and down the court during a "conditioning test" on Saturday, before he limped off the court in Waltham. The Celtics held out a slim hope Shaq would be able to make his return in their Eastern Conference quarterfinal series against the Knicks or possibly in the conference semifinals, if they advanced. "If he were to come back, it would have to be a miraculous recovery," said the source, who requested anonymity. "And at his age (he turned 39 on March 6) and physical condition, the Celtics have planned accordingly."
Nothing official, but if the source is to be believed, this can't be good. (h/t Red's Army)
Update: Doc: Shaq has shown improvement, could possibly play Sunday | Celtics Town - I give up. No idea what's happening or who to believe. Let's just see who suits up game to game.
