Napoli goalkeeper David Ospina has been taken to hospital after collapsing following a head injury during a Serie A game against Udinese.
Ospina, who is currently on loan from Arsenal, suffered a cut to the head early in the first half after colliding with Udinese winger Ignacio Pussetto while tying to cut out a cross.
Ospina received treatment and continued to play, but collapsed shortly before half-time and was stretchered off before being taken to hospital for tests.
Italian media reports said a CT scan was clear but Ospina will remain under observation for the next 24-48 hours.
Second-placed Napoli won the match 4-2 after Udinese had fought from 2-0 down to get back to 2-2. A Dries Mertens goal secured the points for Carlo Ancelotti`s side.
