Jurgen Klopp is hopeful Jordan Henderson will avoid becoming the latest first-team regular on Liverpool's injury list following his early withdrawal on Saturday.
England midfielder Henderson reportedly experienced hamstring tightness before being replaced at half-time of the narrow 1-0 win away to Huddersfield Town.
Naby Keita and Sadio Mane missed the match with hamstring and hand issues respectively while Mohamed Salah, James Milner and Virgil van Dijk all started under injury clouds.
The visitors ultimately secured three hard-earned points thank to Salah's first-half strike, with Henderson's fitness now the focus in the wake of a taxing international break.
"I hope so," Klopp told reporters when asked if the skipper's substitution was precautionary.
"It was not that he felt nothing but he didn't feel a lot. He wanted to carry on – that's a good sign. We decided no. Hopefully it's nothing."
