Andrew Bynum says pain in his left knee is keeping him from playing for the Philadelphia 76ers.

Bynum says his injured right is feeling better. Bynum still feels pain in his left knee when he walks and says there's no sense trying to risk making his season debut for the Sixers.

Bynum will have his knees examined again Dec. 20th. Bynum says the worst-case scenario is he'll miss at least another month. But in the best case, he could be ready to start practicing and maybe be ready to play a game about a month from his exam.

Bynum has not or practiced or played for the Sixers since he was acquired in the offseason from the Los Angeles Lakers. He had been recovering from a bone bruise on his right knee and injured his left knee while bowling last month.
