Mark Ballas and Kristi Yamaguchi, Dancing with the Stars

The Dancing curse strikes again.

Dancing with the Stars pro Mark Ballas, who took home season six's mirror ball trophy with partner Kristi Yamaguchi, suffered a groin injury and announced he will have sit out "a couple of weeks" of the shows tour, according to People.

After a performance on Saturday at the Los Angeles Staples Center, the Dancing pro, who was visibly in pain, apologized to fans for not giving a hundred percent. Both he and partner Yamaguchi did, however, pull-off a high energy performance as well as pull off a hip-hop routine with fellow pros Lacey Schwimmer and Derek Hough.

Ballas should be in tip-top shape by the time Season 8 of Dancing With the Stars kicks off on March 9.
