Inter Milan's Felice Natalino may be forced to end his career at just 20 years of age after undergoing heart surgery.
The young defender was rushed to hospital two weeks ago before being taken for surgery at a Milan hospital earlier this week.
His father told La Gazzetta dello Sport: The doctors told us we need to wait for around six weeks until we'll know if Felice can return to playing football."
Natalino has made two senior appearances for the Nerazzurri, but could be forced to retire following the complications.
