Wales to wear black armbands
Brian, the former Neath and Wales prop forward died, aged 44, of a suspected heart attack at his home in Llangolman on Wednesday.
Wales Coach Gareth Jenkins said: “Brian was still a young lad and the tragedy of his death has affected us and his family in so many ways.
“The team want to show their respect for a great and uncompromising player who was also a special human being.
“He came from an area of rural Wales where the winning of a Welsh cap was an incredible badge of honour. He was so proud of his achievements but always behaved with such humility.”
