Morgan Lake has confirmed that she will not compete in the heptathlon at the Commonwealth Games later this month.
The promising 17-year-old was selected by England for the event, which takes place on July 29 and 30, but she has decided to focus on her preparations for the World Junior Championships in Oregon the week prior to the meeting in Glasgow.
"Ultimately, it's right for me and my development to focus on the World Juniors," Lake revealed in a statement. "This has been an extremely difficult decision for me to take as I was honoured to be selected to Team England.
"I want to wish the rest of the team all the very best and I'll be cheering them all on."
Lake will be replaced in the England team by Grace Clements, who won bronze in Delhi four years ago.
