Britain's top 100m breaststroke swimmer Daniel Sliwinski has been forced to withdraw from the London 2012 Olympic Games with a shoulder tendon injury. He will be operated on next week and faces three months of rehabilitation.  

Sliwinski has struggled with the injury for a couple of years but appeared to have put it behind him when he won the 100m at British trials in March in a time just over the minute. The problem has since returned and requires immediate attention.

“It is an athlete’s worst nightmare” he said in a statement released via the British Olympic Association. “I have had a couple of injuries and I need to go back and rebuild the foundations. I am still young enough to think about Rio 2016, but I need to address this injury before it gets worse.”

Sliwinski tweeted that he would be back and was looking forward to a Rio 2016 campaign.
