Liverpool face a nervous wait to learn the extent of Adam Lallana's injury after he was forced to limp off during England's 2-2 draw with Spain at Wembley.
Lallana, 28, enjoyed a superb start to the friendly match, delivering the telling ball that led to Jamie Vardy winning a penalty before stepping up to convert the spot kick himself to give his side the lead.
Shortly after however the former Southampton star was unable to continue after a late challenge from Bayern Munich midfielder Thiago Alcantara and was replaced by Theo Walcott.
Speaking after the draw, which Spain rescued thanks to late goals from Iago Aspas and Isco, England boss Gareth Southgate confirmed the Liverpool star was being assessed by the England medical staff.
"It was a great shame," Southgate said of Lallana's injury. "I have really enjoyed working with him. He is an intelligent footballer who has now begun to add goals into his game and he was quite key to how we wanted to play tonight."
Lallana's injury saw Manchester United's Jesse Lingard moved inside to take up his role, providing a neat display in attack and combining impressively with Manchester City's Raheem Sterling.
Southgate said of the United midfielder: "Great credit to Jesse Lingard, to move position and to be able to pick that role up as intelligently as he did. It was another bright performance from him which is really encouraging."
Following Lallana's first-half penalty, Jamie Vardy doubled England's lead just two minutes into the second half, meeting Jordan Henderson's cross with a superb diving header.
Southgate's side have their chances to see out the game but were made to pay for those missed opportunities when Spain struck twice in the final minutes of the contest.
Former Liverpool misfit Aspas beat Tom Heaton with a superb curling strike to ignite the Spanish comeback, with Real Madrid midfielder Isco drawing level with a precise finish in injury time.
