The injury is not the same as the one that disrupted the Tottenham skipper's start to the season, reported The Guardian.
Initial tests straight after the game on Monday indicated it wasn’t too serious, but the key factor is whether or not he will be fit to face Newcastle United at White Hart Lane on Saturday.
Tottenham’s defensive unit had been unchanged for the past ten games, up until the 66th minute against Birmingham when King needed to be replaced by Noe Pamerot.
