Aug.4 (GMM) Michael Schumacher has called off his participation in a motorcycle race this weekend.



The seven time world champion was scheduled to take part in a Dutch Superbike race during the Rizla Racing Day at Assen in the Netherlands.



But due to his impending formula one return for Ferrari, the 40-year-old has informed the organisers that he will now not be in action, according to the De Telegraaf newspaper.



Schumacher will reportedly simply attend the event instead.
