Another one bites the ballroom dance floor dust.

Danica McKellar tweeted Friday that she’d broken a rib during ballroom practice for Dancing With the Stars with her partner Val Chmerkovskiy.

It’s unknown at this point whether McKellar, who played Winnie Cooper on The Wonder Years, will be well enough to continue on the show, but it would seem doubtful, considering the pain associated with a rib fracture.

And it seems that McKellar‘s injury is putting a toll on the dancing duo. Chermokvskiy tweeted that it has been a “very very tough week” so far.

If the couple needs to pull out of the competition, it will be a shame. They scored a remarkable 36 out of 40 for their cha-cha routine last week and the judges were expecting them to be just as wonderful on Monday’s show.

So…I broke a rib in yesterday's #DWTS rehearsal. Trying my best to pull thru and could use your prayers!! #wanttokeepdancing

It’s not uncommon or surprising to see celebrities suffer from injuries during their stints on DWTS. After all, they don’t do this daily like the pros do and they are using body parts that may get little exercise in their normal lives.

However, despite the pain of broken toes, concussions and ruptured discs, many celebrities and their partners continue to dance through the pain on the show.

This isn’t the first time a contestant has suffered a rib injury. Maria Menounos continued to compete with two broken ribs and a fractured foot during her season in 2012.

And McKellar isn’t the first celebrity to suffer an injury this season.

Billy Dee Williams, 77, withdrew from the competition in March because of a chronic back injury.

From her tweets, it looks like McKellar is going to give it a shot.

When the going gets tough on DWTS, the tough get dancing.

Had rehearsal today.. it's tough dancing with a broken rib. @iamvalc choreographed an amazing routine- fingers crossed I can pull it off! :/
