Vladimir Seldyakov to referee Zenit v Terek
The 39-year-old referee from Balashikha will meet with the blue-white-sky blues for the fifth time in his career.
Seldyakov has taken charge of four Zenit games previously, with the latest being in April 2017 against Rubin Kazan, a match that resulted in a 2-0 win for Zenit.
The match against Terek will be held on Sunday 7 May at the Stadium St. Petersburg and will begin at 19:00 St. Petersburg time.
