The 23-year old, who scored in the 2-2 draw with Manchester City on Sunday, is in doubt for the Three Lions’ meeting with Brazil on Wednesday because of a thigh problem sustained in the Etihad Stadium clash.
"He got a knock just before half-time on his thigh and he wanted to give it a go in the second half," said Red boss Brendan Rodgers.
"I think he will be a doubt for the game on Wednesday, which is unfortunate because he was terrific today.
"His hold-up play, movement and pace was a real threat, and combination with Luis Suarez, Stewart Downing and Jordan Henderson up front was outstanding.
"He is just with the medics at the moment and he will have a chat with our doctors and he will speak with the England set-up.
"They might want to have a look at it but at the moment he is obviously struggling."
