Formula 1 and MotoGP will both pause for a moment before racing on Sunday afternoon, stopping to remember Fausto Gresini.
The Italian team boss, who operated the Aprilia team under the Gresini Racing banner, passed away from COVID-19 complications in February after a long battle with the virus.
Born in Imola, Gresini will be remembered by both the Formula 1 and MotoGP paddocks. A minute's silence will be held at 13:42 on Sunday at Imola, with MotoGP also holding their tribute at the same time at 12:42 in Portimao.
Formula 1 CEO Stefano Domenicali will be joined on the Imola grid by members of Gresini's family while, in Portugal, the Gresini teams from MotoGP, Moto2 and Moto3 will gather at the Team Greseini team box with FIM President Jorge Viegas and Dorna CEO Carmelo Ezpeleta.
The tribute to Gresini takes place on Sunday while, on Saturday, Formula 1 will pay their respects to the late HRH Prince Philip, Duke of Edinburgh, with the third practice and qualifying session times changed to ensure no track action while his funeral is taking place.
