CHICAGO — Injured forward Brian Ching was left off the U.S. roster for the Confederations Cup in South Africa along with defender Frankie Hejduk.

Ching, a Kamehameha Schools alum from Haleiwa, missed the Americans' last two World Cup qualifiers because of an injured hamstring, and Hejduk was sidelined with a groin injury.

Maurice Edu, who had left knee surgery last week, was omitted along with Colorado midfielder Pablo Mastroeni.

U.S. coach Bob Bradley added three players Sunday who were not in the initial training pool for the recent qualifiers: No. 3 goalkeeper Luis Robles, midfielder Ricardo Clark and forward Conor Casey. Clark played well in Saturday's 2-1 win over Honduras but Casey was ineffective.

The U.S. team leaves Monday for the eight-nation tournament, where it plays world champion Italy (June 15 in Pretoria), South American champion Brazil (June 18 in Pretoria) and African champion Egypt (June 21 in Rustenburg) in the first round.

The roster:

Goalkeepers: Brad Guzan (Aston Villa, England), Tim Howard (Everton, England), Luis Robles (Kaiserslautern, Germany)

Defenders: Carlos Bocanegra (Rennes, France), Jonathan Bornstein (Chivas USA), Danny Califf (Midtjylland, Denmark), Jay DeMerit (Watford, England), Oguchi Onyewu (Standard Liege, Belgium), Heath Pearce (Hansa Rostock, Germany), Jonathan Spector (West Ham, England), Marvell Wynne (Toronto)

Midfielders: Freddy Adu (AS Monaco), DaMarcus Beasley (Glasgow Rangers, Scotland), Michael Bradley (Borussia Moenchengladbach, Germany), Ricardo Clark (Houston), Benny Feilhaber (Aarhus, Denmark), Sacha Kljestan (Chivas USA), Jose Francisco Torres (Pachuca, Mexico)
