Jurgen Klopp returned to Liverpool training on Thursday after visiting hospital the day before.
The Reds boss missed training Wednesday as he attended a hospital appointment as a precautionary measure after feeling ill.
Klopp had said he felt unwell after a charity trip to South Africa.
The Reds released a statement on Wednesday, saying Klopp's trip to hospital was precautionary.
“Jurgen Klopp has attended a hospital appointment today as a precautionary measure, after feeling ill. He is being assessed by doctors and will be absent from training on Wednesday as a result,” the statement read.
He was back at Melwood on Thursday, however, to oversee training as normal.
