Rio 2016: Greg Rutherford freezing sperm as Zika virus precaution

Rutherford's partner Susie Verrill told Standard Issue magazine that they harbour serious concerns over the virus, which experts say is to blame for a surge of cases in Latin America of microcephaly - a serious birth defect in which babies are born with unusually small heads and brains.

The pair, who want to have more children, are as a result taking precautions ahead of Rutherford's defence of his long jump gold medal.
