Tom didn't go into any more details, but his face was somber. And just minutes earlier, they were cheering on their fellow competitors.
Did Melissa suffer an injury during her Paso? Or did something happen backstage that neither we, nor the audience, saw?
We'll keep you updated with details as they come in.
UPDATE: Melissa has tweeted that she suffered a "mild whiplash and concussion," but that she is safe and resting. She also thanked fellow contestant Gavin DeGraw: "@GavinDeGraw bless your heart for carrying me down those stairs!" No word on how Maks will take the news that his dance partner needs bed rest, but we're guessing not well!
