Spain suffered a setback when shooting guard and team captain Juan Carlos Navarro missed Tuesday’s 82-70 victory against Australia.

The Spanish are the biggest threat to the United States in the Olympic men’s basketball tournament, but their chances of scoring an upset in the medal round will decrease if Navarro is unable to play.

Coach Sergio Scariolo said Navarro sustained another foot injury near the end of Spain’s tournament-opening win over China on Sunday.

“It was very strong and all of a sudden,” Scariolo said. “It is nothing related with his former problems. It is a probably a new injury. It is plantar fasciitis.”
