The Tottenham Hotspur captain received a second yellow card for kicking out at Liverpool defender Ibrahima Konate before being ordered off the field by referee John Brooks during a 2-1 defeat.
Romero’s dismissal left Spurs down to nine men as Xavi Simons had already been shown a red card for serious foul play in the first half.
Argentina centre-back Romero had first been booked for dissent after complaining he had been pushed by Hugo Ekitike when the forward scored Liverpool’s second goal.
Romero’s red card means he will serve a one-match ban, missing Sunday’s match away to London rivals Crystal Palace.
But he now faces additional punishment, and a longer ban if found guilty. He has until January 2 to respond to Wednesday’s charge.
Spurs travel to Brentford on New Year’s Day before hosting Sunderland on January 4 and visiting Bournemouth three days later. (AFP)
