Scotland loose forward David Denton has been forced to retire from professional rugby after an 11-month battle with concussion.
The 29-year-old, who has been capped 42 times by Scotland, suffered a blow to the head while playing for club Leicester Tigers last October and has been advised to retire on medical grounds.
"My actual reaction at the time my neurologist told me it was no longer a good idea to play rugby... to be honest, there was a bit of relief," he said after receiving the news.
"This had been building up inside of me for four to five months. By the time I got to it, I had been through all the emotional highs and lows, so I was prepared for it.
"Personally, I think World Rugby is doing as much as it can to try and limit the number of incidents," he added in reference to the game’s governing body’s decision to trial news rules limiting the tackling area to the waist and below ahead of the 2023 World Cup.
"Controlling tackles above the shoulders has been a positive step but I think making anything above the waist illegal would cause more trouble than good.”
