Senegal are through to the knockout stages for the first time since 2002 with a 2-1 win over Ecuador.
Sarr won a penalty just before the break when Hincapie crashed into him, and he coolly stepped up to slot it home.
Ecuador pushed after the break and equalised from a corner when Caicedo tapped in from close range, but just two and a half minutes later, Senegal took the lead again.
Idrissa Gueye’s free-kick deflected to Koulibaly and the captain volleyed in the winner to send his side through.
Ecuador have failed to make it past the group stage of the World Cup in three of their four appearances in the competition, while this was their first defeat in the tournament in five matches (W2 D2).
Senegal became the first African nation to beat a South American side at the World Cup since Cameroon v Colombia in 1990, ending a 21-game winless run (D4 L17).
