Lazio players Stefano Mauri and Giuseppe Sculli have been called for questioning by the Italian Football Federation as part of an ongoing investigation into match-fixing.
The duo will meet prosecutor Stefano Palazzi next week to discuss issues with Lazio's top-flight matches against Genoa and Lecce in May 2011.
Earlier this year, Juventus head coach Antonio Conte was punished for allegedly failing to report his knowledge of two incidents of match-fixing.
He was initially banned for 10 months but has since seen the sentence reduced to four months.
