Fiorentina midfielder Edoardo Bove has been taken to hospital after collapsing on the pitch during his side's Serie A match against Inter Milan on Sunday.
The match was suspended after the incident in the 16th minute.
The 22-year-old suddenly fell to the ground, causing a stoppage in play with both sets of players immediately signalling for the medical staff to enter the field before forming a protective ring around him.
Bove was taken away on a stretcher and put into a waiting ambulance after the referee asked both players to leave the pitch before suspending the match.
