Rodrigo Bentancur appeared to suffer a serious injury early on in Tottenham's Carabao Cup semi-final clash with Liverpool.
The midfielder, who has just returned from a ban, started in midfield for the game, though his night lasted just a matter of minutes before he hit the deck in concerning scenes.
Tottenham started brightly in the game, and were setting up for an attacking corner with Bentancur in the box alongside a number of his other team-mates.
He dived to head Pedro Porro's corner, but appeared to land awkwardly, laying unmoved on the pitch as play continued, with Liverpool goalkeeper Alisson forced into action.
