"Well, we spoke to her and unfortunately she had to leave the tour because her father-in-law is really, really sick and she decided that she needs to spend more time with the family," Savchenko told TooFab. "Family comes first and our hearts go out to her and we pray that he'll be better and he'll recover and he'll fight through, but we will miss her."
"She missed the last tour when she was supposed to be in it and she is missing this one that has everyone in it, but Morgan is covering her so it will be fun," he added.
ABC confirmed to TooFab Thursday morning that Larson will be filling in, and Carson's partner last season Frankie Muniz will also continue his journey on the tour.
Carson took to Instagram Wednesday to announce her departure from the tour due to her father-in-law, Kevin McAllister, battling pancreatic cancer.

Regardless of the cast shakeup, Savchenko is promising an entertaining show.
"The tour's going to be great," Savchenko said. "We're opening the show on the 30th. We've been rehearsing for about a week and a half now, super exciting. It's going to be the biggest tour yet. We have 12 dancers and 2 celebrities."
As for the next season of "Dancing With the Stars," which will only feature all-star athlete contestants, Savchenko is hoping to be paired with an Olympic champion figure skater, who is not too old and not too young and also has a little bit of dance experience.
When asked if he'd be interested in getting paired with Tonya Harding, the pro was definitely game. "Totally, that would be amazing!"
