Three Italian players will be investigated by world tennis' anti-corruption unit after they were suspended by their national federation for match fixing.

The 143rd-ranked Marco Cecchinato and his lower-ranked compatriots Riccardo Accardi and Antonio Campo were banned for up to 18 months by the Italian federation this week for influencing the outcome of matches.

In an email to The Associated Press, the International Tennis Federation says the Tennis Integrity Unit has asked the Italian federation to provide it with the evidence on which the sanctions were imposed.

The ITF says "once this evidence has been received and passed through the standard TIU investigative process, a decision will be made as to whether to charge (the three players) with a corruption offense under the Tennis Anti-Corruption Programme."
