Former Scotland and British and Irish Lions head coach Sir Ian McGeechan says he has been diagnosed with prostate cancer. The former centre and fly-half won 32 Scotland caps, captaining them nine times, and toured with the Lions in 1974, winning the series in South Africa, and in 1977. He coached Scotland to the Five Nations Grand Slam in 1990 and led the Lions to series victories as coach in 1989 and 1997. The 78-year-old is currently consultant director of rugby at Championship club Doncaster Knights. McGeechan told the Telegraph, external he had just completed a six-week course of radiotherapy. "I don't want to make a big thing of it, but it is important to get the message out about urging people to go and get tested," he said. "I said that to our players here, to make sure they get themselves tested. "I have an opportunity here at Doncaster and I have a good family, and I just don't think any differently. I am trying to do all the right things for my health and fitness."
