The International Olympic Committee (IOC) has not commented on injury-related incidents at the Sochi Olympics.

The IOC Medical Commission is gathering and monitoring information about illnesses and injuries. But at this stage we see nothing that would be different from the norm, we have no data that would be different from the previous Games, IOC Director of Communications Mark Adams told a press conference at the main media center in Sochi on Sunday.

But of course this by no means diminishes the significance of yesterday's incident (Maria Komissarova's injury), he added.

It would be inappropriate for us to comment on it as this is a medical matter. But all of us, including the IOC, are wishing her a swift recovery, the spokesman said.

We have no further details. I do not know what the matter was: either the format, or the track itself, Adams added.

As regards another Russian athlete, Mikhail Maksimochkin who was injured in a ski jumping accident, the IOC advises media to refer questions to the sporting federation, he said.

"I would not comment on her (Komissarova's) condition now. Medical services are doing whatever is necessary. We are wishing her a swift recovery," Sochi 2014 Organizing Committee's Vice President Alexandra Kosterina said, for her part.

Meanwhile, it emerged a few minutes ago that Norwegian snowboarder Helene Olafsen, and apparently her U.S. colleague Jacqueline Hernandez will not be able to continue performing at the Olympics due to their injuries.

Olafsen was injured during snowboard cross qualifying competitions, the Olympic news service said. The athlete fell down and was only able to leave the track on a stretcher. Olafsen suffered a knee injury and has been hospitalized.

During the snowboard cross qualifying competitions Hernandez fell and lost consciousness. She was lying motionless for several minutes and was taken away on a stretcher after receiving first aid. The snowboarder reportedly hit her head against the snow.
