'Dancing with the Stars' Kym Johnson Taken Out on a Stretcher, Hines Ward Reacts

'Dancing with the Stars' dancer Kym Johnson, Hines Ward's partner this season, has just been carried out of rehearsals on a stretcher that's being brought to a L.A. hospital.  No word yet on her condition or what caused the ambulance to be called.

Our cameras caught up with a very serious and concerned Hines Ward outside of the hospital, where he told us that he didn't know what was going on, but was going in to find out.

Kym's rep states that she injured herself during rehearsals today and was taken to the hospital for precautionary measures, to assure that she is ok.

The dancing duo has remained a favorite to win the Mirror Ball trophy in the show's 12th season, consistently receiving high scores from judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli.

Watch tonight's ET for exclusive footage of Hines Ward reacting to Kym's injury.
