Harry Kane's ankle looked worryingly swollen in the moments following England's disappointing 0-0 draw with the USA.
The Tottenham man had a scan earlier in the week, but was deemed fit to maintain the captain's armband in an unchanged side for England's second game.
However, Gareth Southgate's squad failed to build on the momentum of Monday's 6-2 win against Iran with the goalless draw at the Al Bayt Stadium, where they struggled to create clear-cut chances.
It meant England failed to secure their place in the knockout phase, and must avoid a heavy defeat to Wales to progress further.
