For those of you wondering as to what happened to Bynum's surgery (initially reported to be on July 18 - supposedly it was delayed because his surgeon did not have any earlier openings), here's some info. This surgery is for a minor meniscus tear, not any tendons or fractures, and thus complications are unlikely.
From the piece:
"Fortunately for Bynum and the Lakers, his Achilles is fully healed, and he’s confident that recovery from the minor knee surgery won’t cut into his offseason plan to improve his core strength, footwork and finishing moves."
Sounds all good.
