On Friday afternoon, Zach Pfeffer was called up for the US U-20 camp taking place in Linz, Austria, April 18-26.

Philadelphia Union fans will naturally be wondering if that means the midfielder will be unavailable to play at PPL Park against New England Revolution this Sunday, April 19.

Union press officer Chris Winkler confirmed to PSP and on Twitter that Pfeffer will leave for the US U-20 camp after Sunday’s game.

Big congrats to @ZachPfeffer_27 on the U20s call-up. He will be available for selection Sunday. Flying out after.
