The Jambos manager was reported to the SFA compliance officer after a touchline incident with referee Alan Muir during a league game against Kilmarnock at Tynecastle.
Sergio was sent to the stand by the referee and later charged with “misconduct including offensive, abusing or insulting language or behaviour and adoption of aggressive behaviour towards a match official.”
The Portuguese manager was found guilty and will now miss five league games against Dundee United, Inverness Caledonian Thistle, St Johnstone, Celtic and Dunfermline.
It is Sergio’s second disciplinary appearance at the national stadium in two weeks, and has the right to appeal.
He will return to the dugout on Christmas Eve when Motherwell travel to Tynecastle.
