Per a release from the Spurs:
Manu Ginobili suffered a nasal fracture in the third quarte rof tonight’s Spurs-Mavericks game. X-rays taken at the AT&T Center confirmed the injury.
Tomorrow Ginobili will be re-examined by Spurs team physicians at which time he will undergo a CT scan. Additional details will be announced after his examination.
The injury will undoubtedly cause Manu pain and discomfort, but the odds of him missing any playing time from this point on are roughly equivalent to the Mavs winning Game 3.
