Wonder Years actress Danica McKellar announced she broke a rib while rehearsing for Dancing with the Stars. She took to Twitter about midday Friday to announce the injury, which took place Thursday. So...I broke a rib in yesterday's #DWTS rehearsal. Trying my best to pull thru and could use your prayers!! #wanttokeepdancing— Danica McKellar (@danicamckellar) April 25, 2014 But she was right back at rehearsing later Friday, despite the news. Had rehearsal today.. it's tough dancing with a broken rib. @iamvalc choreographed an amazing routine- fingers crossed I can pull it off! :/— Danica McKellar (@danicamckellar) April 26, 2014 McKellar is next set to dance in Monday night's episode of the television series. She scored a 36 out of a possible 40 during last week's performance.
