Livorno midfielder Piermario Morosini has died in hospital after suffering a cardiac arrest during his team's Serie B match at Pescara this afternoon.
The 25-year-old collapsed in the 31st minute and received treatment on the pitch - reportedly including a heart massage in a bid to resuscitate him - before being rushed to hospital.
The match was abandoned and the players left the field in tears.
