The two-year-old daughter of Surrey bowler Matt Dunn died last month aged two from a rare form of epilepsy called Dravet Syndrome that affects about one in every 15,000 children born in the UK.
Members of the family are running 5km every day next month to raise awareness of the condition and to raise funds for Dravet Syndrome UK and the Surrey and Middlesex players will wear special commemorative caps that will then be auctioned off.
“We’re incredibly grateful to the cricket family for the support we have received over the last few weeks," said a statement from Matt and wife Jessica Dunn.
