According to reports, the Mexican has exhausted the constructors' champions' patience, with securing second place his objective over the remaining five races.
Mercedes' Lewis Hamilton is 30 points adrift but capable of surpassing Perez, a damning scenario that appears likely to lead to the dismissal of the latter.
The pressure is also growing externally, with Red Bull's online followers making their feelings clear and openly urging Christian Horner to make a drastic change.
And a recent X post from the team has added further fuel to the fire.
Following the news that the Belgian Grand Prix will remain on the Formula 1 calendar until 2025, Red Bull opted to mark the occasion with a throwback picture.
However, the photo selected featured Max Verstappen and former sparring partner Ricciardo, a move that led to countless commenters sharing their confusion.
As exclusively reported by GPFans, Perez has no plans to retire from the sport, with the rumours described as "a load of nonsense" by a source.
But should he continue racing next year, it may not be with Red Bull.
Ricciardo is set to return for AlphaTauri at the United States Grand Prix, having completed his recovery from a broken hand, and will replace Liam Lawson.
Lawson caught the eye during his brief first spell at the top of motorsport and would represent a trustworthy option for AlphaTauri should they lose Ricciardo.
