Grosjean's performances have been under the spotlight after a spate of early-race incidents over the course of this campaign - which resulted in a race ban at Monza for causing a pile-up at the Belgian GP.
Lotus is waiting to see how Grosjean responds to the pressure he has been under to not get involved in more accidents – but in Abu Dhabi he again hit trouble after suffering a puncture in a collision with Nico Rosberg early on.
He later retired from the race when, while battling hard with Sergio Perez and Mark Webber for position, he was involved in a crash.
Speaking to AUTOSPORT, Boullier said that he did not feel Grosjean was to blame for what happened at the Yas Marina, and says the events will not have any impact on the Frenchman's future with the team.
"This fight with three cars ended in a crash, but we cannot blame him as it was a racing incident," said Boullier.
"There is no concern. Obviously he did not have the best qualifying here, but we know why.
"He had a good start but unfortunately he had a puncture. I think we then tried to gamble in pushing the tyres to the end of the race, but he lost his tyres earlier than expected."
