"Melissa was taken by ambulance to a local hospital where she is currently being examined," the reality TV star's representative told People yesterday evening.
"She was accompanied to the hospital by her husband, Tye Strickland, and her dance partner, Tony Dovolani. Everyone is taking all necessary precautions at this time."
Rycroft was released from the hospital late Sunday night, according to E! News. However, whether she'll be able to perform on either of this week's two special performance shows seems uncertain.
"Thank you so much for sending your prayers..still seeing and talking to docs this AM, will give more details soon, but thanks for your love!" Rycroft tweeted Monday morning.
Dovolani has clearly been worried about his Dancing with the Stars: All-Stars partner since the incident occurred. Rycroft reportedly fell onstage while doing camera blocking for a group "Team Dance" number to be featured on tonight's episode.
"Really concerned about [Melissa]..... we don't know if we are dancing tomorrow !!!!! Please keep us in your prayers," Dovolani tweeted late Sunday night.
"Thank you all for your prayers [Melissa's] health is the most important to me ! So fingers crossed that she's ok," the pro dancer subsequently tweeted Monday morning.
Due to tonight's presidential debate, there will be not be a Dancing with the Stars: All-Stars elimination this week. Instead, the show is splitting its usual two-hour weekly performance show into one-hour performance shows on both Monday and Tuesday nights. Half the eight remaining couples will perform their individual routines each night.
In addition, the four couples do not perform their individual dances on a given show will perform their special "Team Dance" performance instead. Rycroft and Dovolani are set to perform in their group's "Team Dance" tonight and dance their individual routine tomorrow night.
