Liverpool boss Jürgen Klopp confirmed Trent Alexander-Arnold and Luis Diaz will have scans on their injuries.
The duo were casualties in the Reds' high profile defeat to Arsenal in the Premier League on Sunday.
The Reds were beaten 3-2 at the Emirates Stadium, despite battling back to equalize twice against the Gunners.
Post-game, Klopp told his post-match press conference: “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 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."
