Tottenham goalkeeping coach Nuno Santos has been fined £8,000 and banned from the touchline for one match for "improper conduct" during Spurs' 1-1 draw with Newcastle on Sunday.
Santos was sent off for his reaction to Newcastle being awarded a penalty by the video assistant referee after a controversial handball decision.
An FA spokesperson said he used "abusive and/or insulting language" towards a match official.
Santos has accepted the charge.
VAR awarded the penalty for handball in extra time after Newcastle striker Andy Carroll headed a cross against Eric Dier's arm from close range.
