Mercedes ace George Russell has welcomed the FIA's rule change that will ease the porpoising issues he and Mercedes team-mate Lewis Hamilton have faced this season. The F1 governing body published a technical directive ahead of this weekend's Canadian Grand Prix which contains measures to limit and eliminate cars' bouncing problems after Hamilton suffered with severe back pain at last weekend's Azerbaijan Grand Prix.

"It's promising to see that they've made action on this straight away and it's not taken them weeks and months and political decisions to change something like this," Russell said. "When it comes to safety, things need to be resolved ASAP. So I'm pleasantly - not surprised to see it come in so quick - but I think it's good for everyone."

Porpoising issues have affected a number of teams on the grid
