They’ve just lost 2-1 to Panamá (partly because the president of Liberia’s son stupidly got himself sent off after 18 minutes).
That leaves Panamá and the USA both with 3 points after 2 games – BUT Panamá have the easy opponent left (Bolivia) and USA have the hard one (Uruguay).
So if Uruguay beat USA (probable) and Panamá draw with or beat Bolivia (very probable), the USA are out.
The United States of America has now officially been eliminated.
