Will Stevens is set to drive for Marussia in FP1 at the Japanese Grand Prix at Suzuka.

The 23-year-old Briton was most recently with Caterham but left after Tony Fernandes sold the team to a group of Swiss and Middle Eastern investors advised by Colin Kolles. While Stevens has experience of the 2014 Caterham from the Silverstone mid-season test, Friday will be his first official practice session.

Stevens is expected to replace Max Chilton for FP1, and Chilton himself said he is confident it won't impact on his own weekend.

"I know Will very well," Chilton said. "He's a good friend of mine so I'm more than happy to do so. I started karting against him at the age of nine and we've always been pretty close friends. We play golf with each other probably once a month so I'm more than happy [to miss FP1] if that comes about.

"I'm really happy for him. Suzuka is one of those track where it is quite important to be in the car all weekend because it is quite a challenging circuit but I got on quite well here last year. I qualified quite a way ahead of Jules [Bianchi] and we managed to get ahead of both Caterhams here, so I'm confident I've got the pace here.

"But that's the way it is; we've got to let these - I say young guys but he's only a month younger than me - we've got to let people get that experience because it's hard for them to get the Super Licence and the mileage done and this is the best way to do that. It makes it slightly easier for me that he's a friend of mine but I think it should be more pushed throughout the grid that maybe every team should do it regularly in FP1 to get the driver's mileage up."
