Rebellion Racing’s Bruno Senna expects to be out of action for six weeks after fracturing his ankle during free practice at Silverstone.
The Brazilian crashed heavily at Copse during the first free practice ahead of the British round of the World Endurance Championship.
Free practice was red flagged for half an hour for barrier repairs and Senna was taken to the medical centre, where they diagnosed a fracture in his right ankle.
“It’s just part of racing,” he told Read Motorsport. “This is the first time I’ve had a serious injury from racing.
“Everything is ok, it’s not a major thing. I’m just going to get it checked and get going to the physio and make sure that it’s not for too long.
“It’s normally about six weeks, so I should be alright for Fuji.”
The next round of the WEC’s super season takes place in October, giving Senna eight weeks to recover before joining team-mates Neel Jani and Andre Lotterer.
In the mean time, Jani and Lotterer will run as a duo in the 6 Hours of Silverstone.
