Sergio Aguero could line up for Manchester City against Leicester at the weekend after the club eased worries about his health following a dressing-room incident on Argentina duty.
The Argentinian Football Federation said Aguero fainted at half-time in Tuesday's 4-2 friendly defeat against Nigeria in the Russian city of Krasnodar, and he was taken to hospital, however City stated he was always conscious.
The Manchester City striker scored after 36 minutes in Krasnodar to put Argentina 2-0 ahead, but did not come out for the second half and was replaced by Dario Benedetto.
The Argentinian federation stated in a Twitter post: "(Aguero medical bulletin) He fainted and was therefore transferred to carry out routine checks just as a precaution."
It later added that Aguero had left hospital and was "at the hotel with the rest of the delegation".
City expect Aguero back in Manchester for a medical check-up ahead of the Premier League match at Leicester on Saturday.
The Premier League club announced on their website: "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."
Speaking after his team let their early lead slip away, Argentina manager Jorge Sampaoli said on the federation website: "Sergio (Aguero) got dizzy and had to leave at half-time."
Aguero suffered a rib injury in a car crash in Amsterdam during October but swiftly returned to City duty, and on this occasion he may be back in action within days.
Aguero recently beat Eric Brook's goals record for City, his strike against Napoli in the 4-2 Champions League win on November 1 taking the forward to a total of 178.
Unbeaten City have raced clear at the top of the Premier League with 10 wins from their opening 11 matches this season and beat Arsenal 3-1 before the international break.
