Sir Bruce hosted Strictly for a decade until he stepped down last year.
Last week, he was forced to pull out of presenting a BBC variety show after slipping and falling at his home.
But the 87-year-old is expected to recover in time to co-host Strictly's Children In Need special, which will feature four stars from Call The Midwife, to be aired on 13 November.
Actors Jenny Agutter, Laura Main, Stephen McGann and Jack Ashton will compete in the one-off contest as part of BBC One's Children In Need telethon.
Children In Need will be hosted by Sir Terry Wogan, Tess Daly, Fearne Cotton, Rochelle Humes and Nick Grimshaw.
The evening will also feature Harry Hill giving his own history of television, while The One Show's Matt Baker and Alex Jones will perform the lead roles in the West End version of The Rocky Horror Show.
EastEnders pub The Queen Vic will host "a house band with a special guest lead vocalist" and stars including Ellie Goulding, Rod Stewart and Selena Gomez will be in the studio.

Jocelyn McKay is now 81 and said she feels "released" from the feelings that gripped her for so long.
"I may be old, but at least I am happy," she told BBC News NI.
"I hadn't really lived until I got the operation.
"For years I felt I was in the wrong body and it wasn't until I was 69 that I plucked up the courage to ask for help."
It was only after a trip to Manchester with some friends, during which Ms McKay lived as a woman, that she realised the surgery was something she needed.
"I was a cross-dresser, I went away dressed as a man and I came home dressed as a man, but in between times I was a woman," she said.
But cross-dressing was not good enough for her.
When Ms McKay returned from her trip, she visited her GP, who referred her to a specialist.
She said: "I had been going to the doctor for a range of ailments and he said to me: 'Thank God you've finally told me what's wrong.'"
Every week three or four people present themselves as transgender to the Regional Gender Identity and Psychosexual Service at Knockbracken in Belfast.
They typically make contact with the clinic through a GP referral or a drop-in facility every week.
200 people are currently being treated by the clinic with 50 more on the waiting list.
More than half of them are aged between 18 and 25.
The number of adults going to the clinic is doubling year on year.
The clinic provides adults with assessment, psychological support and onward referral for hormone replacement therapy and surgery where appropriate.
A gender identity panel to strategically look at the issues facing transgender people met for the first time at Stormont on Monday.
It was formed by the peer support group Focus - The Identity Trust.
It comprises politicians from Sinn FÃ©in and the Alliance party, as well as a Presbyterian minister, the Reverend Lesley Carroll, and others with a long-standing interest in human rights.
The Sinn FÃ©in minister Megan Fearon said the gathering was about "bringing marginalised people together, giving them space to discuss transgender issues and engaging with politicians in a way that had not been done before".
"Transgender people still experience discrimination in nearly every walk of life," she said.
The panel will address trans-phobic hate crime and access to health and education.

The Academy Selsey suffered extensive damage and much of its contents was destroyed in the blaze on 21 August.
The school's 453 pupils are currently being taught at four locations in the Selsey area.
As well as classrooms, the temporary buildings will house science labs, workshops and food technology areas, the school said.
The buildings, some of which have already been placed on the site by two large cranes, had previously been used to house staff and students from Bohunt School in Worthing while building work was carried out.
Tom Garfield, head teacher of the academy, said: "We are absolutely delighted to see the first temporary school buildings arrive on site. It's a great milestone for us, the staff and students alike."
He said once the remaining structures had arrived over the next few days the school would begin preparing the rooms for teaching.
Sir Bruce Forsyth is to return to Strictly Come Dancing for a special Children In Need edition of the show.
