(Reuters) - Romain Grosjean's Mercedes test remains on next month but he will not be able to do demonstration laps at his home French Grand Prix after changes to the Formula One race calendar on Friday.
The French round has been brought forward a week to June 20 and now clashes with an IndyCar race in America that Grosjean will be competing in.
The Frenchman's test, in Lewis Hamilton's 2019 title-winning car, is scheduled for June 29 -- seven months on from a fiery crash in Bahrain in what turned out to be his last race in Formula One.
Mercedes team principal Toto Wolff made the offer of a test as Grosjean lay in hospital with burns to his hands.
Grosjean's Haas car split in half and erupted in a fireball after penetrating a metal barrier on the opening lap at Sakhir, with the Frenchman managing miraculously to extricate himself and leap clear.
"I guess it’s going to be important for many people to see me in a Formula One car after what happened to me," he said in the sport's latest 'Beyond the Grid' podcast.
"You may have loved me, you may have hated me. What happened to me is something you wish for no one."
