Barcelona striker Sergio Agüero was taken off in the 40th minute of Saturday night’s 1-1 draw with Alavés at Camp Nou.
The Argentine went to ground with breathing difficulties and was attended to by the club’s medical staff. A stretcher was initially brought on but fortunately, he was able to make his own way off the pitch.
It was Agüero’s first La Liga start at Camp Nou for Barcelona but he was replaced by Philippe Coutinho after just 41 minutes.
The former Manchester City player was then taken to hospital for a cardiac examination, according to FC Barcelona.
“Kun Agüero reported chest discomfort and has been admitted to the hospital for a cardiac exam,” Barcelona said in a statement.
