After repeated swipes from ”a buckle” during rehearsals throughout the past week and in her paso doble on Monday night’s performance show, Dancing With the Stars contestant Kelly Osbourne has suffered a sprain and minor contusion in her foot, reports MSNBC. Week 5 has already been a sickly one for DWTS — a flu bug affected dance pros Mark Ballas and Derek Hough, whom Maksim Chmerkovskiy replaced as contestant Joanna Krupa’s partner Monday night. Hough is currently “back in action,” while Osbourne plans to dance Monday after a few days of rest.
