Grant Denyer's wife Chezzi breaks down over fears he'll end up in a wheelchair

Grant Denyer is on bed rest in a Sydney hospital as he continues to recover from a ruptured disc that left him unable to walk or sit. 

And on Thursday, Grant's wife Chezzi Denyer broke down in tears during a live radio interview while updating fans on her husband's condition.

Speaking on 2Day FM's Grant, Ed & Ash, the mother-of-two said: 'I don't want him to work anymore, because I'm really worried he's going to end up in a wheelchair.'

Grant and Chezzi married in 2010 and share two young daughters: three-year-old Scout and seven-year-old Sailor. 

While she put on a brave face at the start of the interview, Chezzi fell apart when asked how she and her children were coping.

She said: 'Sailor said the other day, and it broke my heart... I'll probably cry, but because she's been having nightmares, she said, "I just want daddy to come home".' 

Chezzi added that Grant left the hospital on Sunday 'feeling great', but on Monday 'he was pale and looked really unwell and the doctor said, "You better come back to hospital".'

She continued: 'He loves what he does and that's my biggest torment. I'm trying to be the good wife and say, "Okay, well this is manageable and this is not manageable" -  but I can see that it breaks his heart that he's not back at work.' 

Radio presenter Ash London responded: 'I said this to Grant and I know Ed [Kavalee] agrees, there's no pressure from us [for him] to get back to work.

'We want him to rest, to take time off, and I believe that good will come out of this. We love him!'
