Athlete Jade Johnson has been forced to quit Strictly Come Dancing after she was unable to dance for the second week running due to injury.

Johnson had to pull out of last Saturday's show at the last minute after sustaining a serious knee injury during dress rehearsals.

Tests revealed she had torn ligaments in her knee - and her future in the show hung in the balance after she was unable to train with dance partner Ian Waite this week.

She had still hoped to dance up until Saturday, despite BBC doctors advising her not to.

However she was ruled out of this week's show - and has been forced to forfeit her place in the competition as contest rules state that any contestant who misses more than one week has to quit.

 Johnson, who appeared with Waite on Saturday evening's show, said she was "very emotional" after footage of her time in the competition was screened.

"I'm so sorry," she said. "Just sitting here is really hard for me."

Waite also expressed his disappointment at Jade's departure from the show.

"Jade's developed so much as a person as well as a dancer, it's been such a journey for the two of us," he said.
