The turbulent Formula One career of Daniil Kvyat has hit another hurdle as the Russian driver has been dropped for the Mexican Grand Prix in favour of New Zealander Brendon Hartley.
According to BBC Sport, Hartley, who finished in a respectable 13th position in his debut race on Sunday, will have the final three races of the season to stake a strong claim for a position with the team in 2018.
After being dropped by Toro Rosso for the Malaysian and Japan races, Kyvat was given a lifeline for the U.S Grand Prix after his teammate Carlos Sainz left the team to join Renault.
Emerging driver Pierre Gasly, who is thought to be in prime position to replace Sainz at Toro Rosso in 2018, was also unavailable for the race as he was set to race in Japan's Super Formula - which actually ended up being cancelled due to a typhoon.
Speaking to Sky Sports ahead of the race, Kvyat was open minded about his racing future.
"If you're asking me if I have a Plan B or C, yeah I do have a few thoughts.
"Formula 1 is not everything. There are other good opportunities in this life.
"For now, as long as I'm in here I will always try to keep on fighting to stay here as long as possible. But I also miss fighting for the wins and victories and to be honest I don't see how this can happen being here."
Kvyat finished 10th in the race in Austin, claiming his fifth point of the season but for Toro Rosso bosses, it was not enough as for the third time in 18 months, they have dropped the Russian, more than likely ending his spell at the manufacturer.
Realistically, the writing was on the wall early last year for Kvyat when he was dropped from Red Bull to make way for the young Dutch star Max Verstappen.
From then on, it has been a constant struggle - scoring just nine points from his last 39 races with the Toro Rosso team - culminating in the latest turn of events where he has been replaced yet again.
The positive thing is that at the age of 23, Kvyat is still a "baby" in the context of Formula 1.
Whether this setback means that he returns to the Formula 3 series or takes a different route in Motorsport racing, he has a chance to show he can rebound from a difficult period in his career
Hartley, 27 has split his racing career between the Formula 3, FIA endurance series and being a reserve driver for Red Bull and Toro Rosso.
While the door closes for one driver, for Hartley there is a priceless opportunity to be a full-time Formula One driver.
