Another week calls for another substitution.

Although Season 8 of Dancing with the Stars was riddled with celebrity injuries, Season 9 has been hit on the professional side. Two weeks ago, Derek Hough was temporarily replaced by Maksim Chmerkovskiy when he was hit with the flu. Now, Lacey Schwimmer is using up one of her sick days.

On tonight’s broadcast, Anna Trebunskaya will play the part of Mark Dacascos’ partner. Anna originally stepped in this weekend to help the Iron Chef America star rehearse, but her role later increased when Schwimmer’s condition worsened. Unfortunately, this last-minute shuffling only gave the pair two days to learn two dances (the samba and a group paso doble.)

So how is Lacey feeling right now? Well - according to a tweet from earlier today, not great. “Guys I’m super sad to be sick today. Ugh,” she wrote.
