That would mean the English international is forced to sit out of Thursday night’s crunch League Cup semi-final against Tottenham – a match Liverpool have to win to keep alive hopes of defending their title.
Spurs will carry over a surprise 1-0 advantage from their first-leg meeting earlier this year, with an FA Cup clash against Plymouth Argyle to follow at the weekend.
But considering hearts had been in mouths when Alexander-Arnold went down injured against Bournemouth, the prospect of him not missing any Premier League matches at all will be considered a positive outcome by Arne Slot and Liverpool fans alike.
Slot had commented on the injury in the aftermath of the weekend win, saying: “He sat on the floor and we had to take him off – he felt something.
“I cannot tell you exactly what it is and how bad it is of course because we are one hour after the game, but it’s never a good sign if a player is asking for a substitution.
“This is not a fact but I would be surprised if he plays on Thursday, but let’s hope he’s back with us as soon as possible.”
Away from the Alexander-Arnold injury, Joe Gomez, Curtis Jones and Diogo Jota have all returned from problems of their own in recent weeks, with Slot boasting a close-to-fully fit squad.
It comes ahead of what promises to be a hectic few weeks and months for Dutch manager, given his side are still fighting strong on all four fronts.
With a six-point lead at the top of the Premier League table, the Reds faithful are dreaming of a second league title in five years.
While heading into the Champions League knockout stages, the six-time winners are favourites to take home a seventh crown come the end of the season.
