Andrew Bynum said he had his injured right knee drained again today and plans to undergo surgery to mend torn meniscus on or about July 18. He plans to attend the World Cup first, however. He plans to depart for South Africa at the end of the month. Bynum injured his knee during the Lakers’ first-round playoff victory over the Oklahoma City Thunder. His effectiveness came and went, but he managed to play all 23 playoff games. He revealed today that he was asked during his exit interview with Coach Phil Jackson and General Manager Mitch Kupchak if he could have played another game. He said he could have done so. Fortunately for him and the Lakers, there was no Game 8 of the NBA Finals.
