Carneiro and Jon Fearn were dropped from the team’s bench after the game against Swansea, as the coach felt the doctors were being “impulsive and naive” following the removal of Eden Hazard.
She subsequently left the club and was reportedly consulting lawyers about a possible claim for constructive dismissal against the Premier League champions.
Video footage then emerged of Mourinho’s reaction towards Carneiro and a formal complaint was made from a member of the public.
“Following information brought to the attention of the FA regarding Chelsea manager Jose Mourinho and alleged discriminatory comments made in the Premier League fixture between Swansea and Chelsea on 8 August, The FA has now concluded an investigation into the matter”, a statement read.
She is now considering her legal position.
The FA analysed footage of the incident, including the audio recordings, following accusations the Portuguese used abusive language towards Carneiro.
The former Real Madrid manager was visibly unhappy with Dr. Careneiro during the Blues’s 2-2 draw with Swansea City on the openind day of the season, but the FA have announced it “is satisfied that the words used do not constitute discriminatory language under FA Rules”.
West Londoners Chelsea were down to 10 men at the time and it meant Hazard had to leave the pitch, briefly leaving them with just nine.
The Portuguese’s comments attracted plenty of scorn, but the 52-year-old was unrepentant and earned further condemnation when it was announced Carneiro would no longer attend club matches or training sessions.
Carneiro, born in Gibraltar to a Spanish father and English mother, thanked people on Facebook for their support in the aftermath of the incident, but has not spoken publicly since.
Mourinho, however, was heavily condemned by medical professionals for his part in the incident.
Heather Rabbatts, the FA’s only female board member, was vocal in her support of Carneiro, who she said had acted “properly”.
Meanwhile, the Football Medical Association said it was “disappointed” after its efforts to negotiate a return to Chelsea for the ex-club doctor failed.
