When Sen. John Warner (R-Va.) was asked during a speaking engagement in Bristol, Va., Saturday if his wife was with him, he replied "No, she fell on the ice and busted her finger. She was just not able to travel."

Asked yesterday for details of this, the latest mishap of actress Elizabeth Taylor Warner, the senator's office said there was really nothing to it.

She was in New York "in connection with her career" the night of Feb. 15 when she slipped on the sidewalk and broke the little finger on her left hand.

She was treated the following day when she returned to Washington, the spokesman said, "but she's been in a great deal of pain."

In New York, the actress' agent, John Springer, gave a slightly different version.

The accident, he said, occurred not Feb. 15 but Feb. 8. Mrs. Warner had been in New York to receive an award from a Harlem youth center "for her work with children." The next morning, Springer said, while leaving the Regency Hotel, she slipped and fell on a Park Avenue sidewald.

The cast, he said, came off last weekend.

During Warner's rece for the Senate last fall, his movie actress wife was hospitalized after chokin on a chickenbone, twisted her ankle on the way to a campaign meal and also was treated for an injury suffered when a sliver of metal became lodged under her eyelid while she was eating pizza in a Richmond restaurant.
