Antawn Jamison looking for his shot -- and some pain-free days with Cleveland Cavaliers

This is not the way Antawn Jamison envisioned any of this. Not at all.

It's not the way the Cavaliers power forward thought he'd begin his 13th season -- with his left knee ballooning intermittently for an unknown reason, with his shot not falling and with an unexpected role as a sixth man for a team that has limped to a 1-3 start.

The knee was good enough for practice Thursday -- the first time since playing in Saturday's game against Sacramento -- though Jamison is still questionable for Friday's game at Philadelphia. The 34-year-old has had an MRI and tests that show nothing structurally wrong, and while surgery hasn't been discussed, Jamison also said he is "not going to deal with it throughout the season."

If it sounds like Jamison is frustrated, he is.
