May 5, 2014 — -- Amy Purdy isn't the only celebrity who is struggling with injuries on "Dancing with the Stars."
Danica McKellar admitted a few weeks back that she also hurt her ribs.
"So...I broke a rib in yesterday's #DWTS rehearsal. Trying my best to pull thru and could use your prayers!! #wanttokeepdancing," McKellar tweeted on April 25.
For celebrity duel night, also the quarterfinal round, McKellar told ABC News Radio she isn't going to let the pain from the injury ruin the tango she and her partner, Val Chmerkovskiy, have planned.
Chmerkovskiy said he is going to tailor the dance to her injury.
"We're just going to have to be creative, choreographically, and very careful when we're working," he told ABC. "But I definitely don't want to tone it down, it's like finish line, pretty much. We're almost there. We can't afford to make it too simple."
"Dance Moms" star Abby Lee Miller will serve as guest judge on Monday night's show, which starts at 8 p.m. ET on ABC.
