Manchester City striker Sergio Agüero was rushed to hospital after he fainted during half-time of Argentina's 4-2 defeat to Nigeria in Krasnodar, Russia.
According to a report on website Tyc Sports, the Argentine collapsed in the dressing room during half time of the international friendly on Tuesday before he was immediately transferred to a hospital in Krasnodar.
Agüero, who scored the second goal for Argentina in their shock defeat to Nigeria, was replaced by Darío Benedetto in the second half.

Man City released a statement on Tuesday night, updating supporters on the condition of their all-time leading goalscorer.
It read: "Sergio Aguero has been cleared by doctors to return to Manchester as planned after suffering a dizzy spell during Argentina’s 4-2 defeat by Nigeria in Krasnodar today.
"Sergio never lost consciousness, and was taken to hospital for precautionary medical checks. He will be assessed by the club’s medical team ahead of this weekend’s Premier League trip to Leicester City."
Lionel Messi was absent for the two-time World Cup winners, who opened the scoring through Ever Banega and Agüero.
Kelechi Iheanacho, Agüero's Manchester City team-mate, pulled a goal back for Nigeria just before half time with a free kick.
A second-half collapse from Argentina's defense allowed Arsenal forward Alex Iwobi to score twice while Brian Idowu also scored in the victory for Nigeria.
Argentina's Javier Mascherano said: "Playing against a team of such physical strength you pay the price. They walked all over us... and when we tried to get back in the match, we couldn't."
Argentina only secured their spot in the next World Cup in the last round of South American qualifiers and have not delivered convincing performances without Messi.
