Obvious reds!

First Red card

It looked pretty obvious to me, because the attacker went studs up into the defenders ribs! So I don't know what the players from Santos were arguing for.

Second Red

It came after the final whistle when a player from Santos pushed an opponent with "excessive force" and was sent off for "Violent Conduct."

Suspension

After the Final whistle and the red card, players from both team went into a scramble and had to be pulled back by security and team-mates. I wouldn't be surprised if CONCACAF did hand out a few suspensions before the second leg in Mexico.
