Jamison was forced to leave Monday night's game against the San Antonio Spurs in the third quarter with tightness in the back of his knee. He underwent a follow-up exam and MRI, which a team spokesman said was "good."
Jamison, who has had soreness in his knee most of this season, will continue daily treatments. He scored 17 points before leaving Monday's win.
The Cavs acquired Jamison last month in a trade with the Washington Wizards. He said he experienced similar stiffness in his knee while with the Wizards but was able to improve it with rest and rehab.
Jamison plans to play on Friday when the Cavs visit Philadelphia.
