The Chelsea doctor Eva Carneiro has decided to leave the English Premier League football club - six weeks after criticism from manager Jose Mourinho.
Carneiro had her role downgraded after Mourinho said his medical staff were "naive" for treating Eden Hazard during the 2-all draw with Swansea on August 8th.
Chelsea asked Carneiro to return to work, but she has decided not to and is now considering her legal position.
The Football Association is looking into a complaint that Mourinho used abusive or sexist language towards her.
Chelsea say they do not comment on internal staffing matters.
Carneiro and head physio Jon Fearn went onto the pitch to treat midfielder Hazard in the closing stages of the draw with Swansea.
It meant the Blues were temporarily reduced to nine men, with goalkeeper Thibaut Courtois having been sent off, and Mourinho said the duo had been "impulsive and naive".
Carneiro lost her place on the bench and was no longer allowed to attend matches or training sessions.
