Ginobili, 36, was diagnosed with the early stages of a stress fracture in his exit physical with the Spurs. It's an injury that appears to have developed late in San Antonio's championship season, sources told Yahoo Sports.
Ginobili is seeking a second medical opinion before proceeding, sources said.
The recovery and rehabilitation process for the injury are expected to be two months, and Ginobili should be fully functional for the start of training camp in late September, a source told Yahoo.
It's a crushing blow for Argentina, as this may have been Ginobili's last appearance with the national team. Two months won't impact Ginobili's season next year, and in fact, the time off from basketball could help his body recuperate from two long seasons in a row. Either way, even if he wasn't ready, it's not like Popovich will avoid resting Ginobili anyway. He could miss the first half of the season, just to take naps.
But it's unfortunate for Argentina, and there's always a concern about players at that age suffering a stress fracture.
