Liverpool midfielder Thiago Alcantara's hamstring injury is "not good", but boss Jurgen Klopp hopes the Spaniard will be fit to return in a month.
Thiago, 31, had to be substituted after 51 minutes of Saturday's 2-2 draw against Fulham at Craven Cottage.
Liverpool are already without midfielders Curtis Jones and Alex Oxlade-Chamberlain.
"We have injuries, that's how it is. It is a question of how long will the players be out," said Klopp.
"Thiago is good but the injury is not good. I read four to six weeks. I would prefer four."
