Jessica Ennis-Hill has been forced to pull out of a second event because of an Achilles injury.
The Olympic gold medalist had hoped to begin her outdoor season in Edinburgh on Saturday but was advised not to compete because of her injury.
Now the 27-year-old has confirmed she will also sit out the Diamond League event in Oslo, which gets underway on Thursday, after being advised to not risk aggravating the injury by returning to competition too soon.
“I am so frustrated as I want to get out there and start my season, but am being advised to look longer term and focus on a plan that enables me to be in the best shape for the World Championships in Moscow in August," she said.
"Things are getting better and the stiffness is improving – but not quite as quickly as I would have liked."
Ennis-Hill will look to win her second World Championship gold in Moscow later this summer to add to the medal she won in 2009.
For now though the Heptathlete says she is focusing on here recovery and getting back to action as soon as possible.
"My next planned event is the Combined Events Challenge in Estonia at the end of the month," she confirmed.
"But I know that my coach, Toni Minichiello, will be looking at the race calendar for the next few months and making a few new plans!”
Ennis hasn't competed since she claimed gold at the Olympics in London last summer.
