"Dwyane Wade's relationship with Shaquille O'Neal is fractured but the Miami Heat star said he'll always appreciate O'Neal's impact on his career.

Boston Celtics coach Doc Rivers said O'Neal was ruled doubtful for Wednesday night's Game 5 and beyond because of a lingering Achilles injury that is getting worse.

It leaves open the possibility that O'Neal's career could be at an end. O'Neal has a player option for next season but continuous injury problems and the specter of a lockout means there's a chance he has played his last game."
