Jurgen Klopp will be unable to take charge of Liverpool in today's Premier League game against Sunderland due to a suspected bout of appendicitis.
The German coach will hand touchline duties to his first-team coaches Zelkjo Buvac, Peter Krawietz, Pepijn Lijnders and John Achterberg.
Liverpool will welcome the Black Cats to Anfield at 3pm on Saturday with Buvac expected to lead managerial and press duties.
Klopp has been admitted to hospital and, as of yet, it is unclear how long he will be out of action. The Reds face West Ham in an FA Cup replay on Tuesday, which he is unlikely to be back for.
An official statement said: "Liverpool manager Jürgen Klopp will be absent from today's Barclays Premier League fixture against Sunderland at Anfield, after suffering a suspected bout of appendicitis.
"First-team duties will be overseen by the remaining members of the coaching staff, including Zeljko Buvac, Peter Krawietz, Pepijn Lijnders and John Achterberg."
Ironically, Klopp's start to life at Anfield has been plagued by injury thus far. A number of players – including Danny Ings, Jordan Henderson and Daniel Sturridge have been unavailable to the German coach for large swathes of his stewardship.
Now, he faces a spell on the sidelines himself, but Liverpool fans will still be expecting three points against Sam Allardyce's struggling Sunderland. A win could see Liverpool elevate themselves into seventh position above Southampton while Sunderland need a win to keep touch with Norwich in 17th place.
