Alli was substituted for Chelsea midfielder Reuben Loftus-Cheek with ten minutes remaining at the Volgograd Arena, and the knock has been confirmed by England's media manager Andy Walker.

"Yes, it is true - Dele Аlli to have a scan on his thigh after picking up an injury against Tunisia," he said.

England's next match is against Panama on Sunday at 10:00pm AEST.

Thanks to Harry Kane's injury-time winner, they sit second on goal difference in Group G, behind Belgium, who eased to a 3-0 win over Panama in their opening game.
