The Metropolitan Opera has announced that Wolfgang Koch has withdrawn from the fall run of “Tosca.”

The company announced that Koch, who was set to debut with the company, had to withdraw due to illness. As a result, Željko Lučić will sing the role of Scarpia on opening night on Oct. 25 and Claudio Sgura will sing the remaining six performances in the fall.

The two singers join soprano Sondra Radvanovsky and Joseph Calleja, who will portray the title role and Cavaradossi, respectively.

Lučić returns to the production he originated last season on Dec. 31, 2017, alongside Sonya Yonchecva and Vittorio Grigolo.

Meanwhile, Sgura will make his Met debut after the role of Scarpia in such houses as the Carlo Felice, Vienna State Opera, Palm Beach Opera, and Savonlinna Festival.

Koch is expected to return for March performances and make his Met debut then.
