Milan:The Italian Olympic Committee's anti-doping prosecutor has indicated he may open an investigation into a genetic therapy being used to treat the injured thigh of AC Milan forward Ronaldo.
"I'm waiting for news, and it's not been said that we won't open an inquiry," prosecutor Ettore Torri told the ANSA news agency Monday.
Ronaldo is receiving the therapy - called growth factor which uses a natural protein to stimulate cell proliferation - in Brazil under the supervision of national team physician Jose Luis Runco. The practice is banned in Italy.
"I'm waiting for some answers from the Italian soccer federation and I will also ask the Olympic committee's physicians for an opinion," Torri said.
Ronaldo was hurt July 31 during Milan's pre-season training and hasn't played since.
Milan's physicians originally diagnosed Ronaldo's injury as a muscle strain and said he could return against Siena on Saturday. Further tests have revealed a more serious tear that could keep him out another month.
"We made a mistake in our first evaluation," Milan medical coordinator Jean Pierre Meersseman was quoted as saying on the club's Web site Monday. "I'm in contact with Runco who has explained to me what he intends to do. We're opting for a noted therapy called growth factor."
