The Associated Press is reporting that Miami Heat center Shaquille O'Neal had an MRI on his ailing left hip on Tuesday and that he could miss an 'indefinite' amount of time.

Pat Riley does not expect O'Neal to play when the Heat take on the Spurs on Thursday although the team did not release the results of the MRI exam.

O'Neal left Miami's game against Cleveland on Monday to have his hip re-taped and returned to the floor with a significant limp. He has already missed eight games because of the injury.
