Maria Sharapova will be returned to the national Olympic entry list for the 2016 Rio Games in case the Court of Arbitration for Sport (CAS) issues a positive ruling on her appeal, Russian Tennis Federation (RTF) president Shamil Tarpishchev said.

Two weeks ago Sharapova filed an appeal with CAS against her two-year suspension, which was imposed over anti-doping violations.

"We are closely monitoring the news from CAS," Tarpishchev said in an interview with TASS on Tuesday.

"The decision must be made before July 18. In case of a positive appeal's outcome Sharapova will replace [Ekaterina] Makarova."
