In fact, his seat remains the subject of speculation regarding a full-time Formula 1 debut for Kiwi driver Liam Lawson.
If Ricciardo fails to pick up the pace, then not only does he wave goodbye to any hopes of a Red Bull drive in 2025 and beyond, but maybe to his F1 career too.
As the experienced option for his team this year, his tally of zero points means that he has contributed little in their efforts to sit sixth in the constructors’ standings so far.
And now Helmut Marko has confirmed to speedweek.com that Ricciardo is being replaced during FP1 for the Japanese Grand Prix, with the Italian outfit set to field a Japanese duo behind the wheel at their engine partner’s home race (Honda).
“On Friday, we will use our junior pilot Ayumu Iwasa, an all-nippon team, in training [practice],” said Marko.
“What's more, the Suzuka circuit should suit the Racing Bulls' car.”
Exciting times lie ahead for Japanese fans, with the last time that two drivers from their home nation occupied the grid together was at the 2009 Abu Dhabi Grand Prix, when a fresh faced Kamui Kobayashi finished sixth for Toyota, and Kazuki Nakajima finished 13th for Williams.
