Jose Mourinho could face a five-match touchline ban from the Football Association (FA) for abusive and sexist language directed to former team doctor Eva Carneiro.
The FA is investigating a complaint made against the Chelsea manager for language used during Chelsea's opening day draw with Swansea City.
Mourinho reacted furiously when Carneiro and physio John Fearn entered the field of play to treat Eden Hazard while Chelsea were chasing a late winner at Stamford Bridge.
Both were removed from the Chelsea bench by the Portuguese coach, who was condemned by the members of the medical community for his response.
It's possible Mourinho could now face further repercussions for the episode with the FA reportedly studying video evidence of abusive language made to Carneiro during the incident.
The FA's E3 rule state that managers and players must not use "threatening, abusive, indecent or insulting words or behaviour".
An "aggravated breach" of this rule can result in an immediate suspension of five or more matches, yet the indication is that further evidence would still be required before Mourinho could be charged.
