The Manchester City striker was said to have attended a concert in Amsterdam featuring Colombian singer Maluma.
And mutliple reports out of South America claim the taxi he was travelling in to the airport was involved in an accident that left Aguero with severe injuries.
The Argentina international was reportedly wearing his seat belt at the time but suffered broken ribs as a result of the crash.
The taxi was said to have careered into a pole.
If reports are true, Aguero will certainly miss City’s crucial Premier League match against Chelsea tomorrow.
His former club Independiente seemingly confirmed the news with a tweet wishing the 29-year-old a speedy recovery.
It read: “Force and speedy recovery @aguerosergiokun! All @Independiente is with you at this difficult time.”
Early reports suggest Aguero could be out for up to two months which could potentially see him miss three Champions League matches and a crucial Premier League match against Arsenal next month.
Argentina are also involved in two crucial World Cup qualifiers next week against Peru and Ecuador.
Pep Guardiola has already lost Benjamin Mendy to injury, and he could be out for the season, after it was confirmed he had ruptured his anterior cruciate ligament in the win over Crystal Palace.
Aguero has been key in City’s brilliant start to the season, scoring seven goals in just eight games.
