The "Good Morning America" chief meteorologist hurt her pelvis while rehearsing with her partner Val Chmerkovskiy.
The pelvis injury is causing Zee to have back spasms, according to officials with the show.
Zee, who has been meeting with a physical therapist and resting, won't officially know if she'll be able to dance until Monday, but told ABC News she plans to compete in the finale.
"I'm planning to (perform), so we're going to do everything we can to rest," she said.
Zee is competing against Nyle DiMarco and Paige VanZant for the coveted Mirror Ball trophy.
The two-night season 22 finale of "Dancing with the Stars" begins Monday at 8 p.m. ET/PT on ABC.
