Liverpool captain Steven Gerrard will be assessed over the next 48 hours before a decision is made on whether he is fit enough to face Blackburn in Sunday’s FA Cup quarter-final.
The Reds midfielder has missed the last six matches with a hamstring injury but returned to training this week.
Defender Mamadou Sakho is edging closer to a return after four matches out with a hip problem.
Provisional squad: Mignolet, Toure, Skrtel, Can, Markovic, Henderson, Allen, Moreno, Sterling, Coutinho, Lallana, Ward, Lovren, Johnson, Sakho, Gerrard, Williams, Lambert, Balotelli, Borini, Sturridge.
Liverpool vs. Blackburn Rovers kicks off at 4pm GMT on Sunday, live on BT Sports in the UK.
