Jupp Heynckes will not be in the dugout when Bayern Munich take on Schalke on Saturday due to illness.
The 72-year-old is bedbound with flu, meaning assistant coach Peter Hermann will lead the Bavarian giants at the Allianz Arena.
An official club statement read: “Bayern will have to make do without Jupp Heynckes in the top clash against Schalke.
“The head coach has to stay in bed due to a heavy bout of flu and will not be in the dugout.”
Bayern will hope to restore their 18-point lead at the Bundesliga summit with a victory after RB Leipzig closed in with a 2-0 win over Augsburg on Friday.
