"I came out as a precaution," Nocioni told El Diario Ole de Argentina.
Sixers coach Doug Collins said he has spoken with Nocioni several times.
"He told me [last] Saturday that he was feeling much better, and that he hoped to be ready for the game against Germany," Collins said. "He assured me that he wouldn't do anything to hurt his ability to play for us this season. I'm counting on him to use good judgment."
Argentina coach Sergio Hernandez was quoted as saying, "Let there be no more injuries. I look forward to [having] the 12[-man roster] available again."
The USA finalized its roster yesterday when Celtics guard Rajon Rondo withdrew. Rondo had considered himself on the bubble for the final spot, but had fallen behind the Chicago Bulls' Derrick Rose and the Oklahoma City Thunder's Russell Westbrook.
USA Basketball chairman Jerry Colangelo said Rondo mentioned "some family matters to attend to and some things to take care of before the NBA season."
Of the USA players, only the Denver Nuggets' Chauncey Billups, the Lakers' Lamar Odom and the Dallas Mavericks' Tyson Chandler have more NBA experience than Iguodala.
"The honor is not only much-deserved, but it is a testament to Andre's commitment to the game and a result of his hard work and preparation," Collins said. "I have been in constant contact with Andre throughout this process and I am very proud and excited that he has earned this opportunity to represent our country at the World Championships."
Nocioni came to the Sixers with Spencer Hawes from Sacramento in the trade for Samuel Dalembert. He has 2 years remaining on his contract.
Nocioni entered the NBA as a free agent with the Chicago Bulls in 2004-05, staying with them until being traded to Sacramento during '08-09. He has appeared in 449 career games, averaging 11.3 points and 4.7 rebounds in 24.36 minutes. He appeared in 75 games with the Kings last season, making 28 starts, averaging 8.5 points and 3.0 rebounds in 19.41 minutes.
He helped Argentina to a bronze medal in the 2008 Olympics in China after winning a gold medal in '04 in Greece.
Iguodala has started all 82 regular-season games in five of his six seasons. He led the Sixers last season with 17.1 points, adding 6.5 rebounds and 5.8 assists in 38.53 minutes.
