has tested positive for virus. Their team has decided not to field a replacement for Rossi before Teruel round, making the team has decided to line up only his teammate, Maverick Viñales. As Rossi missed the race (along with defending champion Marc Márquez who was absent since Andalusian Grand Prix due to his crash on the previous round), the first Aragon race marked the first time since 1999 at Rio de Janeiro when no current or former premier class Champion will line up on the grid. On Moto3 class in the same venue, Tony Arbolino, despite testing negative for COVID-19, was forced to miss the Aragon Grand Prix as he had come into close contact with an infected passenger on his flight after the French Grand Prix and was required to self-isolate as a result. He was not replaced for that event and was back to racing at the Teruel Grand Prix. On the early November, three days before the European Grand Prix at Valencia, Tech3 rider Iker Lecuona was forced to sit out of the race, due to Andorran quarantine rules for close contact with individuals who tested positive for the SARS-CoV-2 virus. His brother – with whom he lived in Andorra – and his personal assistant both tested positive for the virus on 3 November, meaning Lecuona was forced into a mandatory quarantine of 10 days minimum. Tech3 elected not to replace him on such short notice. Lecuona also missed the Valencian Grand Prix after he subsequently tested positive for the virus shortly before the beginning of the race weekend, and subsequently the Portuguese Grand Prix on the following weekend. KTM factory test rider Mika Kallio replaced Lecuona in Portugal. Lecuona became the second premier class rider who has missed the race because of the isolation.
