Andrew Bynum will begin post-surgery physical therapy Friday, the Sixers announced Wednesday night.

Bynum underwent surgery on both knees Tuesday in New York. The procedure was performed by David Altchek at the Hospital for Special Surgery.

The team announced Monday that Bynum would miss the rest of the season (really, all of it) with bilateral bone bruises that have caused swelling and pain in both knees.

Bynum will begin his PT at the end of the week and will remain non-weight-bearing for three weeks, after which he will spend an additional three weeks on crutches.

If there's any further update on Bynum, the Sixers will announce it.
