MAX CHILTON'S future in Formula One is on the line as the Briton is out of Sunday's Belgian Grand Prix due to what Marussia describe as "contractual issues".

That, however, is in stark contrast to the line being put forward by the management company representing him.

A statement read: "Max has volunteered to step out of his race seat for the race in Spa to allow the team to attract much-needed funds by selling his seat. Max will attend the race and be on hand to support the team in any way possible.

"Marussia are currently in talks with several new investors and it is expected the situation will be resolved before the next race in the F1 calendar in Monza."

Alexander Rossi, who only joined the team last month as reserve driver after leaving Caterham, will now make his F1 debut at the Spa circuit.

Team principal John Booth said: "Although it was not our intention to offer Alexander the possibility to race this season, in light of the circumstances we are pleased to be providing him with the opportunity to make his grand prix debut this weekend."
