Formula 1 stewards at the Canadian Grand Prix probed both Lewis Hamilton and Fernando Alonso for a pit lane incident during the race.
It happened in the early stages during a safety car period. That was caused by Hamilton's team-mate George Russell, who whacked into a wall to leave debris on the track.
Neither of them wasted the chance for a cheap pit stop. They had been duelling on the track and both Hamilton and Alonso dived into their respective garages for new tyres.
