Jon Lancaster will be back in action in the GP2 Series this weekend, with the English driver listed as being back at the wheel of the #23 Hilmer Motorsports car for this weekend's feature and sprint races at Monza.

Lancaster had previously been forced to step aside at Spa-Francorchamps to make way for Robin Frijns, but this week's news that the Dutchman has lost his test and development deal with the financially struggling Sauber F1 team means that he will not be in Italy this weekend. (See separate F1 story.)

"I don't know what happens now," Frijns admitted on Wednesday. "All I know is I'm sitting at home and everybody is in Monza."

While there has been no official confirmation of the driver change from Hilmer itself, the official GP2 Series now lists Lancaster as driving alongside compatriot Adrian Quaife-Hobbs in this weekend's support races, and the associated Twitter feed confirmed the news.

Lancaster himself tweeted on Wednesday evening: "Arrived in Italy ... how I have missed you."

The Leeds-born driver has already won two GP2 sprint races this year at Silverstone and the Nurburgring and was in sixth place overall in the drivers championship before missing Spa, which has set him back to ninth position.

Meanwhile, Auto GP World Series driver Sergio Campana has confirmed that he will be racing in his home event in GP2 with the Trident Racing team alongside Nathanael Berthon this weekend.

"Being at Monza over the weekend of the Italian Grand Prix is a goal that I pursued on other occasions," said the 27-year-old from Reggio Emilia. "This year the dream came true.

"For me it will be all new, as in the past I only had the chance to go a few rounds with an old GP2 without using Pirelli tires," he added. "I know it will not be easy familiar with a whole new world in a single weekend, but I know the track very well, and this will be an element in my favor. I can not wait to be on track."

Campana will take the wheel of the #21 car in place of Ricardo Teixeira, who had previously replaced Kevin Ceccon in the seat for the Hungary and Spa race weekends.

The Italian is currently in third place in the Auto GP World Series with three wins so far in 2013, including the season opener at Monza back in March. He also won the first race at Marrakech and at Mugello.
