Mark Ballas Injured, May Not Perform on 'DWTS' Tonight

UPDATE: Alan Bersten stepped in for Mark, as he slipped a disk in his back. Mark‘s prognosis is unclear.

Mark Ballas injured his back during Dancing with the Stars rehearsal on Sunday (March 27) and may not be able to perform on the show this evening, E! News reports.

The 29-year-old pro dancer has been sitting out since his injury, and UFC fighter Paige VanZant has been practicing with dancer Alan Bernsten.

Mark and Paige received a score of 21 out of 30 last week, and were expected to dance the Salsa to “Danza Kuduro” by Don Omar featuring Lucenzo.

We’re sending Mark all the best and hope he feels better!
