The only thing I have seen so far is from this morning's SF Chronicle:
VAULTER INJURED: Lacy Janson of Florida State was taken to a local hospital after injuring her neck attempting to clear 13-1 1/2 in the women's pole vault. Janson landed awkwardly in the front of the pit and was attended to by paramedics, who placed a collar around her neck and strapped her on a stretcher. She was able to move her arms while on the stretcher. Janson was later discharged from the hospital.
