So Toro Rosso has just announced that Gasly will be replacing Kyvat for the remainder of the season. I for one wasn't expecting this at all, but I guess it makes sense for them. Most likely STR will be racing Kyvat and Gasly as their main drivers in 2018, so it makes sense for them to give the Frenchman some experience... although you have to wonder how this can hurt Toro Rosso's WCC prospects.
