Wonder Years alum Danica McKellar broke a rib while practicing on Thursday for Dancing With the Stars.

The 39-year-old took to Twitter to let fans know what happened. She tweeted on Friday, "So ... I broke a rib in yesterday's #DWTS rehearsal. Trying my best to pull thru and could use your prayers."

McKellar has done quite well on the show this season, USA Today reports. Ahead of next Monday's episode, she currently sits in third place. She even was one point shy of nearly getting a perfect score on a routine, People notes.

She and her partner Valentin Chmerkovskiy performed a routine based around Beauty of the Beast and were so close to snagging the first perfect score of the season. Judge Bruno Tonioli said the routine was "incredible."

Today notes that the latest season of DWTS has actually seen very few injuries. Actor Billy Dee Williams did have to drop out of the program back in the third week due to arthritis and back issues.
