Former Wimbledon junior champion Laura Robson has called time on her tennis career aged 28.
Robson reached a high of 27 in the world and also claimed an Olympic silver medal alongside Andy Murray in the mixed doubles at London 2012.
A number of injuries and subsequent operations took their toll, however, prompting the decision to walk away from the sport.
"I went through every possibility of rehab and of surgery," Robson told BBC Sport.
"I had another hip surgery and probably did the best rehab block of my life - I went to all the best specialists and had some incredible people that I was working with just to get me back on court - and then the second time I hit, I just knew.
"It feels weird to say out loud, but I'm done, I'm retired. I've sort of known that for a while because of what I was told by the doctors last year, but I think it just took me so long to say it to myself, which is why it took me so long to say it officially."
