What does Shaq’s latest injury mean for struggling Celtics?
O’Neal missed 27 games with foot and Achilles’ tendon injuries and was making his first appearance since Feb. 1. "The update is that it’s not the same injury," Rivers said. "Had nothing to do with the Achilles; it’s a calf strain. It’s not a bad strain, but it’s a strain. So similar to the one Von [Wafer] had but not even close to the severity. Well, ‘I don’t know [when he will be back]’ is the answer."
