Liverpool say midfielder Naby Keita is fine after being taken to hospital with a back injury suffered in the 1-0 Champions League defeat by Napoli.
The Guinean, 23, received treatment on the pitch in Italy before being taken off on a stretcher after 19 minutes.
He has been assessed, with the issue being back pain, and will return home with the Reds squad on Thursday.
Liverpool host rivals Manchester City in the top flight on Sunday and Keita has not been ruled out of that game.
Keita, who joined from RB Leipzig for £48m this summer, has made nine appearances for Liverpool this season, including four starts in the Premier League.
