Great Britain's two-time Olympic taekwondo champion Jade Jones could be tempted to make the switch to mixed martial arts in the future.
The 23-year-old is aiming to add to her gold medals from London 2012 and Rio 2016 by claiming a historic hat-trick at the Tokyo 2020 Games.

"It's hard to get sponsors and make money in taekwondo, but I just love it.
"Maybe in the future I'll go to MMA after I've retired from taekwondo, but for now, no-one in the sport has ever got three Olympic gold medals, so I have to continue to (try to) get that."
American Ronda Rousey took up MMA, going on to become a UFC (Ultimate Fighting Championship) champion, after earning a judo bronze medal at the Beijing 2008 Olympics.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.

That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
