He struck Ethan Ampadu in the forehead with a back kick. Dominic Calvert-Lewin scored the VAR-awarded penalty.
With two games left to play, Tottenham's lead is two points over West Ham, who are below the relegation zone.
Swedish national team midfielder Lucas Bergvall was substituted towards the end, as was James Maddison, who played his first minutes of the season after a knee injury.
