Barcelona striker Sergio Aguero has been admitted to hospital for a cardiac exam after experiencing chest pain during Saturday's 1-1 draw with Alaves.
Aguero, 33, had to be taken off before half-time after being attended to on the Camp Nou pitch by Barca's medical team for a lengthy period of time.
The Argentina International was eventually able to walk off the field before being transferred to hospital where he will undergo tests to determine the nature of the problem.
