Earlier on Tuesday it emerged that de Vries had been dismissed after just 10 grands prix following a disappointing start to his F1 career with the Italian squad.
AlphaTauri has now confirmed the de Vries' exit and has announced that Red Bull third driver Ricciardo will step into the Dutchman's seat for the remainder of the 2023 season.
"Scuderia AlphaTauri announces that Daniel Ricciardo will be joining the team on loan from Red Bull Racing for the remainder of the Formula 1 season, starting from the upcoming Hungarian Grand Prix," the team said in a statement.
“I’m very pleased to welcome Daniel back into the team,” added team boss Franz Tost.
“There’s no doubt about his driving skills, and he already knows many of us, so his integration will be easy and straight forward.
“The team will also profit a lot from his experience, as he is an eight-time Formula 1 grand prix winner.
“I would like to thank Nyck for his valuable contribution during his time with Scuderia AlphaTauri and I wish him all the best for the future.”
Ricciardo returned to the Red Bull family as a third driver after losing his McLaren drive at the end of last year, one year before the end of his contract.
The 34-year-old Australian opted to take a sabbatical to recharge his batteries after a punishing stint with the Woking team, but has been keeping race ready and completed his first test with the current Red Bull RB19 on Tuesday.
