Force India have confirmed Vitantonio Liuzzi has replaced Giancarlo Fisichella for the remainder of the season.
Liuzzi has been promoted from his role as test and reserve driver with the team, a position he has held since the start of 2008.
The 28-year-old will now make his race debut with Force India in front of his own fans at this weekend's Italian Grand Prix at Monza.
Liuzzi, who last drove in Formula One at the end of the 2007 season with Toro Rosso, appreciates he has been given his chance courtesy of the chain reaction sparked by Felipe Massa's accident
"I can't wait to get back into the car in race trim, particularly at my home grand prix in Monza," said Liuzzi, who competed in 39 grands prix over three seasons from 2005 to 2007.
"I really appreciate the opportunity Vijay (Mallya) has given me, particularly now Force India has a great car that's performing very well.
"I am confident I can carry on our progress. I'm very motivated, in good shape and hungry to get some more points on the board.
"Although it's unfortunate this came about as a direct result of Felipe's accident, this is my opportunity to show people what I can do, and I'm really looking forward to it."
Team owner Vijay Mallya, who released Fisichella to Ferrari last week, is confident Liuzzi will not let down the team.
"I'm delighted to give Tonio the opportunity to get back into a race seat, which I know he has been itching to do for the past two years," said Mallya.
"Force India is now in a very competitive position and we need a driver who can continue this momentum.
"This will be the chance for Tonio to demonstrate to both the team and the field he has the commitment, speed and professionalism to perform, and I am sure he will seize this opportunity."
