Naby Keita chose not to travel with the Liverpool squad for victory at Sheffield United.
The Reds saw out a nail-biting 1-0 win after Gini Wijnaldum's strike bobbled through the legs of Dean Henderson in the Blades goal.
Keita, who starred in Liverpool's 2-0 win over MK Dons on Wednesday, was not part of the squad which travelled to Yorkshire for the lunchtime kick off.
The Liverpool Echo says despite making his comeback from injury midweek, the midfielder elected to stay behind at Melwood to work on his fitness.
Before Wednesday, Keita had not featured for Liverpool in five months, and Jurgen Klopp is taking extra precautions in order to ensure the 24-year-old makes a full recovery.
