Backup center Zendon Hamilton was waived Thursday hours before the club would have had to pay his full $719,000 salary for the season.
Before playing the Houston Rockets, the club also activated forward Sasha Pavlovic, who has been out since spraining his left ankle during practice last month. Pavlovic is averaging 1.9 points in 12 games this season.
The 30-year-old Hamilton played in 45 games for Philadelphia last season. He has also played for Toronto, Denver and the Los Angeles Clippers.
