NEW YORK (Reuters) - Veterans Christian Pulisic and Weston McKennie headline the United States' 27-man training camp roster ahead of Copa America but coach Gregg Berhalter said on Monday that nothing was set in stone for the tournament.
The United States host Colombia on June 8 and five-times world champions Brazil on June 12 for a pair of friendlies, before Copa America kicks off on home soil on June 20.
