Red Bull-backed Patricio O'Ward is set to contest this weekend's Formula 2 races in Austria, replacing banned MP Motorsport driver Mahaveer Raghunathan.
Raghunathan reached 12 penalty points on his licence for virtual safety car infringements in last weekend's Paul Ricard F2 round, meaning the team needed a new driver to slot in alongside its regular driver Jordan King.
Reigning Indy Lights champion O'Ward has appeared on the entry list for the event to make his series debut.
He currently drives for Carlin in IndyCar and was made a Red Bull junior driver in May this season.
He was set to compete in two oval events later this season but those outings have been cancelled.
It will not be the first time the Mexican has competed in Europe as he raced in lower formula on the continent in the early years of his career.
O'Ward is the second new driver on the grid at this event, as Arjun Maini has taken over Dorian Boccolacci's Campos Racing for the next two rounds, at the Red Bull Ring and at Silverstone.
