Dancing With the Stars is taking a big hit this season but the show must go on, and they have a few tricks up their sleeve to fill in the holes left by the exits of Derek and Julianne Hough.

One strategy ABC is using to keep their viewers on the edge of their seats is bringing back judge Len Goodman.

Goodman missed the show's 21st season, but announced his return during that season's finale in November.

"I've been watching the show from the U.K., and I must say everyone has been doing a fantastic job," Goodman said at the time, before addressing the DWTS pros specifically. "Listen up: Len is coming back next season, and I don't want any of your nonsense!"

Another plan from the network is to add classic sitcom stars like The Facts of Life's Kim Fields and Full House star Jodie Sweetin.

"FINALLY!!! I can share the fantastic news that I'll be joining @abcdancing this season!! Can't wait!!" Sweetin announced in an Instagram post on Wednesday. "I have the amazing @keo_motsepe as my partner on this wild ride!! #teamkeoandjodie #dwts #season22."

This will be the first Hough-less competition in 10 seasons with Derek leaving to bring Singin' in the Rain to Broadway and Julianne giving up her judge's seat to pursue other projects -- and get ready for her wedding to her fiancé, Brooks Laich, which she has joked about being slow to plan.

"I will miss being on the panel for Season 22, but have a lot of exciting stuff coming that I look forward to sharing," Hough told ET in a statement last month. "The pro dancers, producers and crew at DWTS will always be my family."

"I promise it's not the last you'll see of me in the ballroom," she assured.

DWTS returns Monday, March 21 at 8 p.m. ET/PT on ABC.
