PARIS, Sep 8: All 22 teams will start the 10th stage of the Tour de France after their riders tested negative for COVID-19, organisers told Reuters on Tuesday, adding that four members of staff had returned positive tests. French health authorities and organisers Amaury Sport Organisation (ASO) had said that should two members of a team, riders or staff, test positive for the novel coronavirus, the whole outfit would be excluded from the race.
