Ricciardo was always intended to be Red Bull's safety net. But fluctuating form and a series of decisions leaves the veteran out of F1.

Daniel Ricciardo has been fired by Red Bull Racing and will be replaced immediately by Liam Lawson. Ricciardo knew at the Singapore Grand Prix it was likely his final F1 race.

Ricciardo began as a test and reserve driver for Horner's outfit before being loaned out to secure his debut on track in 2011 with HRT. The now 35-year-old has driven for both the secondary and main constructors at Red Bull over his 14 seasons in F1, but now looks to be out of the sport for good following his mid-season exit.
