Brain injury association Headway has expressed its sadness over the death of Scottish boxer Mike Towell.
Peter McCabe, chief executive of Headway, said the charity was "deeply saddened" about the death of the "young father in the prime of his life".
"Our heartfelt thoughts go out to his family and friends at this difficult time," he said.
"Sadly, this is not an isolated incident. It is another in a long line of boxing tragedies where lives have been lost or irreparably damage as a result of brain injury.
“Only recently, fellow boxing Nick Blackwell was left in a coma following a bout with Chris Eubank Jnr. After that fight, we repeated our concerns that more young men and women are risking their lives by taking part in boxing."
Mr McCabe added: "How many more lives have to be damaged or lost before this senseless sport is banned?”
