The team made the announcement this morning with the following statement:
“We are pleased to announce that Dan Fallows becomes Head of Aerodynamics at Infiniti Red Bull Racing with immediate effect.
Dan has worked as part of the team’s aerodynamic department for many years. Previously working as a Team Leader (Aerodynamics), he left the team for a short time last year. He has now returned to Infiniti Red Bull Racing to begin working in his new role.
We can confirm that Peter Prodromou has commenced a period of gardening leave; we would like to thank him for his valuable contribution during his time with the team.”
McLaren and Red Bull are in a legal tussle over the future of aerodynamics expert Dan Fallows.
Red Bull announced on Wednesday that Fallows had rejoined them in the role of head of aerodynamics, replacing McLaren-bound Peter Prodromou.
In January, McLaren said Fallows had joined from Red Bull, and racing director Eric Boullier said he had a “legally binding contract”.
“The matter is now in the hands of our lawyers,” he added.
BBC Sport has learned that after Fallows agreed his deal with McLaren, Red Bull offered him a better job title and a higher salary.
However a Red Bull statement only said Fallows “left the team for a short time last year and has returned to begin working in his new role”.
The team added Prodromou, who worked closely with their design chief Adrian Newey, is now on “gardening leave”. He will join McLaren ahead of the 2015 season.
Prodromou was previously with McLaren from 1991 until moving to Red Bull with Newey in 2006.
