San Antonio Spurs guard Manu Ginobili has a stress fracture in his right leg and is unlikely to represent Argentina in the FIBA Basketball World Cup in Spain this summer, league sources told Yahoo Sports.

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 is expected to be two months, and Ginobili should be fully functional for the start of training camp in late September, a source told Yahoo.

Ginobili played an immense role in the Spurs' championship season, averaging 12.3 points and 4.3 assists. A future Hall of Famer, Ginobili is a two-time NBA All-Star, the 2008 Sixth Man of the Year, and a four-time NBA champion.
