Connacht's Sean O'Brien has been forced to retire at the age of 26 due to a concussion injury. The flanker who represented his country at U18 and U19 level as well as captaining the Irish team at the U20 Junior World championships in 2014 made his debut for the province in the 2015/16 Challenge cup against Enisey-STM. He also came of the bench in that season in the Pro12 Grand final win over Leinster. Shoulder and foot injuries have curtailed his game time in recent months, with the concussion injury forcing the Galway native to make a difficult call on his playing career.
I’d like to take this opportunity to thank Connacht Rugby for making a young boy’s dream come true, the memories and friendships made will last a lifetime. Not everyone gets a fairytale ending but I will never forget just how lucky I was to be a part of this club. I am looking forward to cheering in the stands."
