Tottenham captain Cristian Romero was charged by England's Football Association with allegedly acting in an "improper" manner in response to being sent off during Saturday's 2-1 Premier League defeat against Liverpool.
With Xavi Simons already being given a red card earlier, Tottenham ended up with nine men after captain Romero was given a second yellow for a tackle on Ibrahima Konate in the 93rd minute.
"It's alleged that he (Romero) acted in an improper manner by failing to promptly leave the field of play and/or behaving in a confrontational and/or aggressive manner towards the match referee after being sent off in the 93rd minute," the FA said in a statement.
Romero has until January 2 to respond to the charge.
The dismissal meant he already has to serve a one-match ban and will miss Sunday's away trip to Crystal Palace.
Tottenham are 14th in the league table with 22 points, 17 behind leaders and derby rivals Arsenal.
