Conor McGregor trial LIVE updates as jury to be sent home after all evidence heard

Medical definition of a bruise

Professor Basil John Farnham, a trained forensic practitioner who examines various types of assault, has told Conor McGregor’s barrister Remy Farrell the medical definition of a bruise – “a bruise is a discolouration of the skin, caused by blunt trauma, and causes little blood vessels to be damaged and blood leak under the skin, and percolates towards the skin.”

“Bruising can show delay in appearance and changes in size and shapes. Bruise may be delayed and may not appear in the exact same position the trauma caused it, tends to blur and changes colour because the red of your haemoglobin goes blue, brown and yellow and fades.

“A bruise can change in size, shape, position and colour.”

He said he also worked as a GP for 40 years and works part-time now. He said foreign objects in the vagina would come up at times – “We all prescribe medications to be given vaginally, e.g. pessaries or hormones.”

He subsequently adds: “If you squeeze it it will still remain red because there is blood under it.”
