Argentina or South Korea is set to become the first nation to qualify for the knockout phase of the football world cup in South Africa.
The two sides play tonight in Johanesburg.
If Argentina win and Greece fail to beat Nigeria a few hours later, the South Americans will advance to the top 16.
Similarly, if the Koreans beat Argentina and Nigeria are unable to beat Greece they'll confirm their place in the next round.
Tonight's other match is France against Mexico.
However the host nation hopes have been left in tatters, by a superior Uruguay side who won three nil, ending a 13-match unbeaten run for South Africa.
With one point from two matches and still to play France, South Africa are set to become the first host nation not to make it past the first round.
In other games, Switzerland caused the biggest upset of the tournament so far in beating Spain 1-nil, while Chile beat Honduras one nil.
