Kristaps Porzingis will miss the FIBA World Cup with a foot injury, costing Team Latvia its best player. The Boston Celtics, however, expect him to be cleared by training camp in October after a four-to-six-week rehab program.

The big man confirmed the news in his native language on social media, saying the plantar fasciitis in his foot is still preventing him from playing after several weeks of rehab and MRIs. He said it was a joint decision between Latvia's medical staff, coaching staff and the Celtics.

It's unclear when Porzingis sustained the injury, but German journalist Rupert Fabig reported there was a potential issue on Aug. 9. The Latvian basketball federation denied the report.
