Last year the Italian international underwent minor heart surgery after suffering an ischemic stroke whilst playing last season, but made his comeback in April before representing his country at Euro 2012.
Hoowever, he has now been given a green light by the medic, who revealed that he has completely recovered from his health problems.
"There are no problems compared to what was seen when he was at Milan," Doctor Franco Benazzo told reporters.
"His heart is fine."
The Euro 2012 finalist scored only seven goals in Serie A 33 appearances during his time at Milan, spending just 18 months with the Rossoneri.
