The Brazilian striker has had numerous injuries since he joined AC just over a year ago now but this seemed to be by far the most serious of the lot and it could end the 30-year old's career.
But AC manager Carlo Ancelotti has rubbished the rumours about Ronaldo retiring due to his latest injury and said “Is Ronaldo retiring? You would have to ask him about that,”
“But he seems fit to me and I haven’t heard anything from him. “If he finds fitness, his contract will be renewed,” Ancelotti maintained.
