Will Stevens is set to drive for the Marussia Formula 1 team during the opening practice session for the Japanese Grand Prix.
The Briton has previously tested for Caterham, but his appearance at Suzuka will be his first outing during an F1 race weekend.
Stevens' outing in Japan could be part of an expanded role with Marussia that may also open up the chance for further outings later this year.
He is currently sixth in the 2014 Formula Renault 3.5 standings, having won the opening round at Monza in Italy.
An announcement from the team confirming its plans is expected later on Thursday.
