Liverpool defender Andy Robertson will be out until after this month's international break with a knee injury.
The Reds will be eager to get their Champions League campaign back on the right path against Ajax on Tuesday night after a shambolic 4-1 loss to Napoli in their opening match.
But they will have to make do without the Scotland captain, who was spotted wearing a knee brace at Liverpool's AXA Training Centre on Sunday.
Speaking on Monday ahead of the game with Ajax, Jurgen Klopp confirmed the 28-year-old will be out at least until after this month's international break.
