Milan - AC Milan defender Mattia De Sciglio could join the club's casualty list after hobbling off injured in a 1-0 Champions League defeat to Atletico Madrid and being taken to hospital on Wednesday.
De Sciglio was on the wrong end of a crunching tackle by Emiliano Insua in the 26th minute of the sides' last 16 first leg, prompting a melee and earning the Argentinian a yellow card.
He played on and was eventually replaced by Ignazio Abate, a change that would prove fateful for the Rossoneri after the defender headed on a corner for Diego Costa to score Atletico's winner in the 83rd minute.
Reports said De Sciglio has suffered an ankle sprain however Milan coach Clarence Seedorf said the true extent of the injury will only be known on Thursday.
"He's off to the hospital but we'll only know how bad it is tomorrow after the tests. It's a shame, he had a great game up until then," said the Dutchman.
Atletico, currently joint top of the Spanish top flight, will now fancy their chances of qualifying for the last eight of the competition for the first time since 1997 when the sides meet at the Vicente Calderon in a fortnight.
