The news emerged last night that the World Cup winner tested positive for cortisone and did not provide the necessary paperwork.
The FIGC has confirmed that the injection of the anti-inflammatory was made on August 29 after Cannavaro was stung by a wasp.
Juventus staff put together the report confirming a medical emergency requiring the injection and sent it to the Italy medical staff, but not to the CONI (Italian Olympic Committee).
"The Juventus medical staff worked in respect of the rules and acted with urgency in August following a deterioration in his condition due to an insect sting," read a statement from the Bianconeri.
"In such an occasion, the pharmacological treatment was necessary to prevent further complications, including lethal ones.
"The player and the Juventus medical staff will, as always, be at the full disposal of the authorities to clarify this matter as soon as possible, including any misunderstandings in the paperwork."
