Liverpool boss Jurgen Klopp is confident Luis Diaz hasn't suffered serious injury.
Diaz was forced off during their 1-1 draw with Arsenal.
Klopp said: I hope not (a serious injury). He has pain. It was knee-on-knee. In that moment we wanted to change twice but Lucho was down.
We first wanted to wait to see if Lucho had to come off, but then we decided to change all three. We don't have to wait to see how Lucho is so that's what we did then.
Lucho told me he felt a little pain. Physios were not too concerned but you never know and we play in three days. You never know. It's a quick turnaround, we have to see."
