September 26, 2009 (Los Angeles, CA)-- THE INSIDER's LARA SPENCER spoke with actress Teri Hatcher, who was a guest on Friday's canceled episode of the "Tonight Show," about the stunt-gone-wrong that injured Conan O'Brien.

Teri tells us she'd recently finished a triathalon, so she and Conan were taping a bit based on that for "The Tonight Show," "We did this bit and at the very end, when we ran in to cross the finish line, he slipped as he was crossing the finish line and hit his head. And the thing was, I was in front of him so I didn't see it initially."

She goes on to say, "He didn't get off floor right a way, but then he [seemed] like he recovered and [pulled] it together, and they did an instant replay, and you could really see his head hit the floor." She continues, "He did go to hospital and he does have a concussion."

Teri adds that she hears Conan is fine and just needs to rest, "I was just a wreck...," she says, "like we had a great day and it couldn't have been better -- and then that was the ending to it, and it was awful you don't want to see anyone get hurt."
