Swiss Moto3 rider Noah Dettwiler must continue to wait for his first race of the season. The 19-year-old from Solothurn has also been ruled out for the Grand Prix of America at the end of March.
Dettwiler had hoped to make his comeback at the third race of the season in Austin after having to undergo two operations - one on his left wrist and later a second on his right elbow - following a pre-season crash.
Medical examinations have now shown that a start would be too early. "The strain of a full GP weekend would simply still be too much," his team said in a press release. The next realistic goal is the Qatar Grand Prix in mid-April.
