Liverpool forward Luis Diaz is expected to be out of action until late December after picking up a knee injury in the first half of Sunday's 3-2 Premier League defeat at leaders Arsenal, British media reported on Monday.
The 25-year-old Colombia international does not need surgery but will likely miss 10 matches in Liverpool's packed schedule ahead of the World Cup, which starts on November 20.
The Reds will hope to have Diaz back for their visit to Aston Villa on December 26 in their first match after the World Cup, which Colombia have not qualified for.
Liverpool's England defender Trent Alexander-Arnold also sustained ankle damage in Sunday's match and manager Juergen Klopp said after the match that both injuries did not look good.
"Lucho (Diaz) we had to change before (halftime). (It's) something with the knee, not good," he said.
Diaz has made 12 appearances in all competitions so far this season, scoring four goals with three assists.
Liverpool have struggled this season and are 10th in the table with 10 points after eight matches. They travel to Rangers in Group A of the Champions League on Wednesday.
