Mohamed Salah was named on Liverpool's bench for their Premier League game against Brighton.
It was his first time in a Reds squad since claiming he had been "thrown under the bus" by the club following last weekend's 3-3 draw with Leeds.
Salah did not travel to Italy for their 1-0 Champions League win over Inter Milan.
The 33-year-old Egyptian is due to head to the Africa Cup of Nations on Monday.
