Sauber have dismissed reports a neck injury could force Pascal Wehrlein to miss part or all of pre-season testing in Barcelona this month as "pure speculations".
Wehrlein was involved in a crash with Felipe Massa at the Race Of Champions last month, with the collision seeing his car flip off the track and hit a barrier.
The German cancelled the remainder of his schedule at the event as a precautionary measure, but Sauber have denied suggestions it could cause him to miss the start of preparations for the 2017 calendar.
However, Wehrlein does remain subject to ongoing assessment.
"Current rumours about Pascal Wehrlein in the media: the medical examinations are still ongoing," the team tweeted.
"Therefore, the reports are pure speculations. We will provide information in due time."

The Circuit de Catalunya will host two four-day pre-season testing sessions, the first of which begins on February 27.
Upon his withdrawal from the Race Of Champions, Wehrlein said: "I'd really like to race again and I feel fine, but the doctors have advised me to rest so of course I will take their advice.
"It's no more than mild discomfort but my real priority for the coming year is my Formula One season."
