"Washington Wizards leading scorer Jerry Stackhouse will undergo exploratory arthroscopic surgery to investigate the extent of damage to the already worn lining on the back of his right knee cap, the team announced yesterday. The length of time the projected starting small forward will be inactive will be determined by the results of the operation, however, President of Basketball Operations Ernie Grunfeld said it was a "safe assumption" that Stackhouse won't be ready for the start of the season."
