Andrew Bynum was not with the 76ers Thursday, instead heading to New York City for a pair of joint-lubricant injections in his afflicted knees.

A Sixers spokesman said the Synvisc injections were previously scheduled with Bynum's personal physician, Dr. David Altchek, and are not to be considered a setback.

Bynum will take the rest of the week off and will resume his basketball-related activities next week, presumably as soon as Sunday.

Bynum previously received Synvisc-One injections in September. It's understood that the lubricant can provide relief from pain for up to six months.

Monday, Sixers GM Tony DiLeo said it was possible that Bynum could participate in practice with the Sixers by Friday. That, clearly, is out of the question.
