Pierre Gasly will replace Daniil Kvyat at Toro Rosso from this weekend's Malaysia GP for an unspecified number of races.
Gasly is expected to land the race seat to be vacated by Renault-bound Carlos Sainz at the end of the season and Toro Rosso have decided to use the upcoming races, starting at Sepang, to evaluate Gasly in a race weekend.
Although reports have suggested Gasly will be in the car for the Malaysia and Japan double-header, the team did not confirm how many races Kvyat would be sidelined for.
