Anna Netrebko has canceled her Bayreuth Festival debut.

The festival announced that due to fatigue, the soprano would not sing the role of Elsa in “Lohengrin.” The soprano, who was set to make her debut on August 14, was ordered three weeks of rest. The cancelation is the second in the past two weeks as Netrebko also withdrew from her second performance of “Adriana Lecouvreur” at the Salzburg Festival.

As a result, Netrebko will be replaced by Annette Dasch, who has sung the role of Elsa during the 2010, 2013, and 2015 festivals. Dasch has also sung the role at the Teatro alla Scala and Deutsche Oper Berlin.

Netrebko is set to return to the stage on August 30 for a concert with her husband Yusif Eyvazov before reprising “Adriana Lecouvreur’ for two concert performances at the Deutsche Oper Berlin.
