Jessica Ennis-Hill: The Olympic heptathlon champion was the poster girl of London 2012
Jessica Ennis-Hill has pulled out of the British Championships in Birmingham this weekend as she continues to struggle with an ankle injury.
The 27-year-old has not taken to the track since winning Olympic heptathlon gold last year.
Coach Toni Minichiello remains optimistic she will be fit to compete at the World Championships in Moscow, but, with that event only a month away, she could well head to Russia having not competed all summer.
Ennis-Hill, who has now withdrawn from four meetings, initially opted to miss the indoor season in the wake of her Olympic exploits and start the outdoor campaign later than usual following her wedding.
She is next scheduled to compete at the Diamond League meeting in Monaco on 19 July but her participation there remains in doubt.
Olympic long jump champion Greg Rutherford has also withdrawn from the British Championships with a hamstring injury he suffered in Paris last weekend.
"I'm hoping to be back on the track soon," he said.
With the event not on Mo Farah's schedule as he prepares for the 5,000 and 10,000m in Moscow, it means none of Great Britain's three Olympic champions will be competing at the flagship event in the British athletics calendar.
