Spurs lose rookie guard after surgery

San Antonio Spurs rookie guard Lonnie Walker will undergo right knee surgery tomorrow and miss the start of the upcoming NBA season, the club announced on Saturday. Walker underwent an MRI exam Saturday morning that showed he had suffered a torn medial meniscus in his right knee in the fourth quarter of a 117-93 pre-season home victory over Detroit.

Spurs team physician David Schmidt will perform the operation, after which a timeline for his return will be determined.
