Former Roma, Inter, Parma and Fiorentina striker Adriano's career is at risk after he snapped his Achilles tendon.
L'Imperatore will be out of action for at least five months after the devastating injury to his left leg.
He had only just signed for Corinthians after terminating his contract with Roma by mutual consent six weeks ago.
Adriano went under the knife in Sao Paolo today and for some weeks he will need to use a wheelchair, then upgrade to crutches.
It is the latest blow for a player whose career has been wracked with injuries and personal problems.
