Britain’s Katarina Johnson-Thompson has said she suffered an Achilles injury at the end of last year.
The heptathlon world champion added that she had spent the last few weeks wearing a boot which would be coming off on Monday.
“This news doesn’t impact my plans for 2021, Tokyo is still very much the focus,” the 28-year-old wrote in a message on social media.
“I look forward to representing Great Britain in my third Olympic Games.”
Johnson-Thompson – who splits her time between Liverpool and Montpellier – won a gold medal at the World Championships in 2019, beating defending champion and Rio 2016 gold medallist Nafi Thiam.
She added: “My rehab is going as well as could be expected and while I am currently at home in Liverpool focusing on my recovery, I will be heading back to Montpellier to begin training again in March.
“Understandably, this is not the start to the year I was hoping for but I’m pleased to be able to share this off the back of a positive few weeks.”
