Saracens flanker Will Fraser has been forced to retire from rugby due to a neck injury.
The 27-year-old was an integral part of Saracens' double-winning 2015-16 season when they landed the European Champions Cup and Aviva Premiership title.
He also represented England Saxons, and was part of the same academy group at the club as players like British and Irish Lions Owen Farrell, Jamie George and George Kruis.
"As everyone knows, I have had a torrid time with injuries pretty much throughout my whole career, but especially in the last couple of years," Fraser said.
"Unfortunately, with this injury, I have had to listen to the medical advice, which has been for me to stop playing. The decision was made for me, which is tough, but it's a decision that completely I understand and accept.
"As I take time to reflect, I can look back on my career with no regrets. There is nothing more I think I could have done or anything else I wished I could have done."
Saracens rugby director Mark McCall added: "Will's attitude, commitment, and selflessness will be his legacy at Saracens. The way he fought back from a number of injuries was an inspiration to us all.
"He is, and will always remain, a Saracens man and boy, The respect and admiration in which he is held among his peers at Saracens cannot be overstated.
"He has played a key role in forging the culture we all enjoy here, and he will be missed."
