The 37-year-old reality star and her pro partner, Tony Dovolani, were forced to withdraw from season 21 after she failed to return to perform on last Monday's live show. Zolciak-Biermann had flown home when she suffered a blood clot that caused a "mini-stroke."
However, on Monday, she revealed that she will return for the finale in November.
"My heart is so heavy not being on the set today of DWTS with everyone, but I'm healthy and happy I finally was able to attend my husband's game!" Zolciak-Biermann wrote alongside a picture of her former competitor, Paula Deen, giving her a shoutout with a sign. "I'll be back for the finale in NOV I'll kick ass."
Although the former Real Housewives of Atlanta star petitioned DWTS to allow her to return to the competition, judge Carrie Ann Inaba shut down any possibility when ET caught up with her last Wednesday.
"I feel bad for her but those are the rules, and you know, I am a strong abider by the rules," Inaba said. "I am the Lift Police so the rules are important to me. I feel badly for her, but it would be unfair to the other competitors."
"I think they handled it right because it could have been Kim going home tonight," he explained." And would it have been fair for her not to dance, and still come back next week, and have someone else go home? That wouldn't have been fair."
"So we don't know what the outcome was, but the rules say, you can't go the next week if you don't perform," he continued. "It truly is unfortunate that she wasn't able to make it here to perform."
