ESPNLA.com's Dave McMenamin is reporting a date of July 28, if you're looking to send a gift or just spend the day praying to the basketball gods.
During Drew's exit interview, he indicated a penciled-in time frame of mid-July to meet the knife. I'm not sure why Bynum opted to go later in the month, but I wouldn't worry about it. His injury wasn't as much serious as simply difficult to play through, especially compared to Bynum's other injuries. Save an unforeseen setback, I'm guessing rehab will continue as planned and he'll be in camp on time and ready to roll.
Also, Lakers.com scribe Mike Trudell says Drew's strained Achilles, which cost him several regular season games down the stretch, has healed up nicely. Fingers and toes crossed, 2010-2011 marks the season where Bynum finally gets through a campaign of big minutes without a hitch.
