Double Olympic medallist Nick Willis is confident he can rediscover his best form in time for next year's Commonwealth Games following under-the-radar post-Rio surgery.
Willis finished a battling eighth in the 1500m world championship final in London, but was satisfied with his effort given an injury-ridden start to the season.
"I haven't told anyone publicly but six weeks after the Rio Olympics I had surgery on a sports hernia double release on my adductors," he said yesterday.
"I spun it that I needed to take three months off for a break as I really didn't want meet directors to know that I was going under the knife and I might miss out on appearance fees the following year.
"That probably played a role in the injuries after that but now I'm fully healthy and still improving," he said.
