Namibia captain Jacques Burger has been ruled out of his country's final pool game against Argentina on Sunday, thereby ending his Test career.
Burger suffered a confirmed concussion nine minutes into the match against Georgia on Wednesday and will not be able to play against the Pumas.
Burger's Test career spanned over nine years and 36 caps which included three Rugby World Cup appearances in 2007, 2011 and 2015. On Wednesday he equalled Hugo Horn's 11 Rugby World Cup appearances for his country.
Before the team's departure for Leicester on Thursday, Burger reflected on his career.
"It was a huge disappointment that I could not complete last night's match and an even bigger disappointment that I will not be able to play on Saturday. I am very proud of my team and it is not the way that you would want to end an international career. But that's the game of rugby for you," he said.
Sunday’s match against Argentina would have been his last for Namibia.
"I was really hoping to finish my international career in style, the emotions were building up to the match on Sunday and to have it ended abruptly like this after just ten minutes is a bit of a setback. But I have no regrets, I have had a wonderful time playing for Namibia with my friends," added Burger.
"A lot of people have asked me why I chose to play for Namibia. I am a Namibian, I grew up with a lot of the guys I am playing with now, played with and against them at school. It was an honour for me to represent Namibia and I have never regretted it."
