The United Rugby Championship could be called in to settle a dispute between Zebre and a group of former players who left the club in the summer.
Richard Kriel, MJ Pelser, Dennis Visser and Kobus van Wyk are among the players who claim that they are still owed money after only getting half of their wages in June and none at all for July.
Instead, they have been asked to settle for a single €3,000 (£2,600) payment, and the players are considering asking league bosses to step in and get them paid in full.
