Tonus sustained a minor concussion at the MXGP of Lombardia on Sunday 27th September during the opening race of the Grand Prix. As a precaution the 28-year-old withdrew from the event and did not take the start for race two, instead heading home to Switzerland for further evaluation.
Rider safety is paramount and following the consultation with his doctor, Tonus and the Monster Energy Yamaha Factory MXGP team decided together that it would be best for the Swiss rider to withdraw from the events in Mantova as an additional precaution.
Over the next week, Tonus’ health will be monitored and his return to racing will be decided only after consultation. All updates will be posted on Yamaha Racing’s social media platforms when available.
