Les Grenadiers can knock Ecuador out of the tournament, while Los Amarillos need to win, ideally by a few goals, to have a shot at advancing to the quarterfinals.
For USMNT fans, it's all eyes on Copa America Centenario's Group B to find out the identity of the United States' quarterfinal opponent.
First up is Ecuador and Haiti.
Les Grenadiers are out of the tournament, having lost both their preceding matches. A narrow loss to Peru in their opening group stage game was encouraging, but then Brazil trampled Haiti in a 7-1 win in Orlando.
