Brendon Hartley's Toro Rosso teammate Pierre Gasly has got the nod to move up to Red Bull Racing as Daniel Ricciardo's replacement for 2019.
Gasly will switch to Red Bull's senior team for next year's Formula 1 season.
Gasly is in only his first full season in F1, but he will now drive alongside Max Verstappen.
Ricciardo stunned Red Bull earlier this month by announcing a move to Renault.
It's possibly good news for Hartley who has earned two points this season, with a strong chance Toro Rosso won't replace two seats for the 2019 season.
