While he hasn't been able to dance, Chemerkovskiy has remained closely involved, working with Morris and Bersten during rehearsals and choreographing many of their numbers -- including this week's Frozen-themed jazz routine for DWTS' Disney Week.
Following their dance, Morris and Bernsten went backstage to talk with co-host Erin Andrews, and they were joined by Chmerkovskiy, who had nothing but praise for their performance.
"I thought that Heather did an amazing performance," he marveled. "I was looking forward to this [dance] the whole weekend and [Bersten] didn't let me down."
That being said, Chmerkovskiy announced that he had finally recovered enough to come back.
"Alan's officially fired," Chmerkovskiy joked before hugging the talented substitute pro. "I'm taking over as of tonight."
For their Frozen jazz number, Chmerkovskiy wanted to create an original move for the routine that would wow the judges, so he came up with an extraordinary lift that Morris and Bersten had never done before.
"I'm doing a special lift and it's kind of something that I'm nervous about," Morris admitted in a pre-taped package. "So, fingers crossed."
During the dance, Morris and Bersten -- who were playing Anna and Kristoff, respectively -- gave a brilliant life to the dance and executed their lift perfectly.
However, the non-traditional jazz routine left the judges divided. Carrie Ann Inaba and Len Goodman wanted more dance content while Julianne Hough and Bruno Toniloi praised the pair's energy and charisma. In the end, they earned a 34 out of 40.
