Philadelphia Union attacker Cavan Sullivan has earned a call-up from the United States for the upcoming September/October FIFA international window, sources told ESPN. The official announcement will take place on Sept. 17, with Sullivan part of the squad set to face Peru, Chile, Mexico and Canada. The USMNT's first game is against Peru on Sept. 26 in Orlando, Florida.

If Sullivan, who turns 17 on Sept. 28, makes his debut in any of those matches, he will be the second-youngest player to play for the U.S., behind only Freddy Adu. Adu first appeared at 16 years, 243 days in a 0-0 draw against Canada on Jan. 22, 2006.

The Philadelphia native signed a homegrown deal with the Union on May 9, 2024, at 14, making him the fifth-youngest player to sign a first-team MLS contract. The deal includes a clause allowing a transfer to Manchester City when he turns 18 in 2027.

Sullivan's recent form has caught the attention of U.S. manager Mauricio Pochettino. Since MLS resumed after the World Cup break, Sullivan has scored six goals and added eight assists. He scored two goals and added an assist in a 5-0 win over San Diego FC on Sunday. He now has nine goals and 15 assists across all competitions this season. Players are expected to begin arriving at the U.S. Soccer National Training Center in Atlanta on Sept. 20.
