Jason Kenny has withdrawn from today's sprint competition following his crash in the Keirin yesterday.
Sprint coach Iain Dyer said: "Jason is feeling very sore after his crash yesterday and didn't get much sleep last night. Having consulted with the team doctor Jason has decided to withdraw from today's competition."
Fellow GB cyclist Lewis Oliva who is riding for the Welsh trade team Team USN will also miss the sprint following a separate keirin crash. Lewis will go to A and E for an x-ray on his hand.
