Hines Ward on Kym's Scary Fall

"Dancing with the Stars" contestant Hines Ward felt horrible about falling on his partner Kym Johnson's neck while they were rehearsing.

"Knowing I had some impact on her getting carted off in an ambulance, I got emotional about it." Hines told "Extra" special correspondent Tony Dovolani. "She could've been paralyzed right now. I couldn't live with myself if that happened."

But Johnson and Hines turned the heat up with their Argentine Tango. A choked-up Carrie Ann praised Hines for supporting Kym through such an excellent dance, and the judges gave them a perfect 30 points. Watch!

The pressure is on with contestant Kirstie Alley as well. She talked with Dovolani about fighting with her partner Maks during their rehearsal. "One thing I said when I did the show was to say, 'I'll never cry like that girl or that girl.' I've done everything."

The "Dancing with the Stars" semi-finalists will find out their fate tonight on ABC.
