UK Athletics announced today that the world and European heptathlon champion, who was due to compete at the Championships which take place at the Bercy stadium from March 4-6, is calling her indoor season to a close.

An MRI scan, Ennis’s third since the injury occurred in mid-February, is reported to have shown positive improvement over the past two weeks but not enough to risk participating in a full pentathlon.

"I have thought long and hard about whether to compete at the European Indoor Championships in Paris this coming Friday, and if I am really honest I just don't want to risk any further damage to my ankle and calf,” Ennis said.

"As it is the inflammation and fluid build up is reducing, and I could potentially get through the pentathlon with medication, but there is no guarantee that it will not worsen as a result, and then mess up the start of my outdoor season. I cannot take this risk the World Championships has to be my priority."

“I would like to wish the rest of the team a really successful Championships."

Ennis and her coach Toni Minichiello consulted with physiotherapist Alison Rose and the UK Athletics  Medical Team when coming to this decision.
