Helmut Marko says Daniel Ricciardo will be Red Bull's third driver in the 2023 Formula One season.
Ricciardo is without a seat on the grid next year after his McLaren contract was terminated 12 months before it was due to end.
The Australian paid the price for a disappointing season in which he has finished in the top 10 just six times, sitting 12th in the driver standings.
Ricciardo had stated that spending time away from F1 could be a "blessing in disguise", but Red Bull advisor Marko revealed he will have a part to play after all.
Marko told Sky Germany ahead of the season-ending Abu Dhabi Grand Prix: "Ricciardo will be our third driver.
"We have so many sponsors, we have to do show runs and the like, so of course he's one of the most high profile and best suited."
Ricciardo spent five seasons with Red Bull before joining Renault for the 2019 and 2020 campaigns.
World champion Max Verstappen and Sergio Perez will remain Red Bull team-mates for the 2023 season.
