Football in Italy is in a state of shock after Livorno midfielder Piermario Morosini collapsed and died during the club's Serie B contest against Pescara on Saturday.
The tragedy has seen the Italian Football Federation (FIGC) postpone all matches which were scheduled for the weekend, and Tommasi is planning emergency talks to discuss medical tests on players.
"This leaves us impotent and disarmed," Tommasi is quoted by La Repubblica as saying. "Something like this is inexplicable.
"We are waiting for more info, any comments right now feel out of place.
"We had a meeting scheduled for Monday, which has been postponed, but we will convene to talk about this tragedy and the issue regarding the safety of players.
"If in professional divisions there are certain guarantees, tens of thousands of players in the amateur divisions undergo very few tests," he concluded.
