Manchester United boss was being blamed for using abusive, insulting or improper language after the 3-2 win at Old Trafford.
But Mourinho has escaped a possible touchline ban for comments made after Manchester United's win over Newcastle, writes
Mirror.
A statement from the FA read: "A charge against Jose Mourinho for allegedly using language which was abusive and/or insulting and/or improper has been found not proven following an Independent Regulatory Commission hearing today.
"It related to an incident at the end of the Manchester United versus Newcastle United game on 6 October 2018.
"Written reasons for the decision of the Independent Regulatory Commission will be published in due course. This decision is subject to appeal."
The full written reasons are likely to be published next week, when the FA's disciplinary department will consider whether to appeal.
