O'Neal hasn't played since a Nov. 12 win over Miami.
Cavs coach Mike Brown said before Saturday's game against Philadelphia that O'Neal won't play in a game again until he practices. The team is off Sunday and doesn't play again until Nov. 25 at Detroit.
The Cavs are being cautious with O'Neal, who was acquired in an offseason trade with Phoenix. Brown is closely monitoring O'Neal's minutes to try and keep him fresh for the second half of the season and playoffs.
O'Neal has averaged 11.3 points and 6.9 rebounds in nine games.
