center Kristaps Porzingis is out indefinitely because of an unspecified health issue and will miss the start of training camp.

Warriors general manager Mike Dunleavy Jr. confirmed the news at Media Day on September 28, saying Porzingis will not travel with the team to Hawaii for training camp.

Dunleavy said Porzingis had been on the court and fully cleared last week before the Warriors were informed on Sunday that he was dealing with a health issue.

Golden State has not disclosed the nature of the issue and there is currently no timetable for Porzingis to return. Dunleavy said the team hopes to have him back soon but could not provide a more specific timeline.

The setback comes less than three months after Porzingis agreed to remain with Golden State on a two-year, $40 million contract.
