I've just learned that Katherine suffered a back injury in a fall mid-dance last night, which may explain why she & Mark finished at the bottom of the judges' scoreboard this week.
Encore Performance of the Week: William & Cheryl's Samba
macy's Create a Dance (Samba)(Chelsie & Tristan): "End of Time" by Beyonce
Musical Guests:
Alanis Morissette: "Guardian"
Cast of "Rock of Ages" (including Julianne Hough & Mary J. Blige): Medley
Carrie Underwood: "Good Girl"
The last team eliminated before the finals is made up of...
...Maria & Derek. Katherine & Mark were saved first, followed by William & Cheryl.
