Naby Keita suffered a possible groin injury in Liverpool's 3-0 defeat to Barcelona in Wednesday’s Uefa Champions League semi-final encounter.
The 24-year-old was left in pain after a challenge from Ivan Rakitic at the Camp Nou, and then walked off the pitch in the 22nd minute and was replaced by Jordan Henderson two minutes later.
Two minutes after his substitution, Luis Suarez opened the scoring for Barcelona before Lionel Messi's second-half double gave the hosts a crucial three-goal advantage.
Egypt's Mohamed Salah and Senegal's Sadio Mane were also in action for Liverpool but they failed to find the back of the net with their shots.
