Sturridge left the squad’s mid-season training camp in La Manga two days early, with his condition failing to improve despite his wish to take part in double sessions in Spain.
With just under a week to go before the trip to the King Power Stadium, Sturridge has reported for training at Melwood, and is expect to be back in contention against the Foxes.
He has played just 136 minutes of football in the league since the turn of the year, having dropped down the pecking order under Jurgen Klopp.
But nevertheless, his availability is a boost for the Reds, as they look to build on their 2-0 win at home to Tottenham Hotspur last time out.
However, Klopp could opt to alternate his attacking options, with Sturridge impressing up front against Leicester back in September.
Marko Grujic (hamstring) is also due back in training this week, with the Serbian having spent a lengthy spell on the sidelines.
He has featured for just one minute in the league since making the £5.1 million move from Red Star Belgrade in the summer, with Klopp taking a cautious approach to his adjustment.
But Grujic’s return will be a boost for the 49-year-old, who will be able to rotate his midfield options further, joining the likes of Jordan Henderson, Adam Lallana, Georginio Wijnaldum and Emre Can.
The centre-back flew to Germany to see a specialist on a knee injury that has persisted throughout the season, after missing the trip to La Manga in the hope he would recover.
There is still time for Lovren to make his return to the squad, but it seems unlikely he will start against Leicester, having already missed the Reds’ last two league outings, against Hull City and Spurs.
Otherwise, however, Klopp has a full-strength senior squad to call upon, as he looks to put together a long winning run before the end of the season in May.
