The pros absence was evident at the top of the show: VanZant entered the ballroom solo.
The rehearsal package showed Ballas lifting a very worried VanZant onto his shoulder.
His strength is okay, VanZant said to the camera.

Mark has a smaller frame.
If you put us next to each other, we are pretty close to each other.
Ive never dropped a partner yet, Ballas responded.
But then he was filmed throwing VanZant through his legs the next day and then stopped the camera blocking.
I just slipped a disc, he was filmed saying.
My back pinched funny.
Oh yeah, Im in trouble.
The show went on for VanZant, who danced with troupe member Alan Bersten.
Im hopeful Ill be back.
VanZant did fine with his choreography: She and Bersten earned 24 out of 30.
