Cavs to sit Shaq for sixth straight game
O'Neal hasn't played since a Nov. 12 win over Miami.
The Cavs are being cautious with O'Neal after acquiring him from Phoenix in an offseason trade. They are trying to keep him healthy the second half of the season and playoffs.
He hoped to play against the Pistons after practicing Monday.
O'Neal has averaged 11.3 points and 6.9 rebounds in nine games.
