"I think it definitely comes with disappointment," Sharna said of being eliminated during a Good Morning America appearance on Tuesday with the former professional bull rider sitting by her side.
"Everybody wants to go all the way. We're competitors at the end of the day but also incredibly grateful we made it to the Top 5 of Dancing with the Stars. How incredibly proud I am of this man. We had no idea we were going to get that far."
Bonner had obvious physical limitations in the dancing competition -- mainly a stiff back -- due to breaking his neck in a 2016 accident when a bull threw him onto the ground and trampled over his head in a crowded arena.
Bonner was briefly paralyzed from the neck down and informed by doctors there would only be a one to five percent chance he'd ever walk again.
"It's something internally that makes him stiff and does stop him from moving, and he does not have the ability that other people do. And so to compare him to [other contestants] is a little unfair," Sharna said on GMA.
"To constantly get the comment, 'Oh, you looked a little stiff.' He's part metal in his spine. He's gonna!"
The pro dancer and Australian beauty also explained it didn't work to Bonner's advantage that he appears fit and strong on the outside. Sharna acknowledged it was probably easy for people to forget Bonner's struggles watching him dance week to week.
"I think it did work against us. He looks so fit. You don't realize he has a disability. It's not Noah Galloway where you can see the amputations and it's not an Amy Purdy where she has no feet," Sharna noted.
Now that Bonner has rehearsed and performed for over eight weeks, however, Sharna revealed he's stronger and more agile than ever. And for that "incredible" turn of events, she's "so thankful."
