The fleet-footed winger sustained what appeared to be a knee injury and it has now been revealed that he would not feature for Liverpool until after the World Cup.
Even though Luis Diaz would not require surgery, he is to spend the next six to eight weeks in the treatment room.
Speaking after the loss to Arsenal, Jurgen Klopp said:
“Lucho we had to change before [half-time]. [It’s] something with the knee, not good.
“He will have a scan and then we will know more. I have no idea about the extent and then on top of that Trent [Alexander-Arnold] is bad as well with the ankle.
“[He] twisted the ankle, not good. Trent never, in seven years, went off if he could have played on. He was in too much pain, it started swelling immediately, so we will have to see.
Since Colombia failed to qualify for the FIFA World Cup in Qatar, the winger can use that time to step up his recovery process.
The loss over the weekend leaves Liverpool in tenth position, 14 points behind league leaders Arsenal.
The Reds face Rangers in the UEFA Champions League on Wednesday before hosting Manchester City in the Premier League.
