Jose Maria Lopez could be set to miss the upcoming Formula E races in Monaco and Paris, saying he will not risk aggravating a vertebrae injury that could rule him out of Le Mans.

Lopez was ruled out of this weekend's FIA World Endurance Championship round at Spa after crashing heavily at Silverstone two weeks ago, sustaining minor damage to two vertebrae.

"I'm fine, nothing to worry about. It's more of a small injury," Lopez told crash.net. "The fact is that. It's small and I have to go through a natural process to heal If it had been maybe bigger, we maybe could have done something, put some cement on the vertebrae. But as I have to go through a natural process, it takes a bit longer.

"For sure it's very frustrating for me and I'm very disappointed to not be able to drive here, because I'm obviously looking forward to drive this car. But there was much more to lose than to win by not doing this race. The main objective for me and the team is to be in Le Mans 100 per cent. This injury will not stop us to be 100 per cent for Le Mans."

While Lopez has until June 18 to be fully fit for the race at Le Mans, he is due to be racing in Formula E with DS Virgin Racing next weekend in Monaco, with another round set for Paris seven days later.

Lopez stressed that he will race if he is able to, but only if he is fit enough and there is no risk of aggravating his injury that could cause issues for Le Mans.

"I will try to do Monaco, as soon as I am 100 per cent and the medics say I am 100 per cent to race," Lopez said. "If there is any minimum percentage that doing the race will cause me still a little bit of danger and take longer in the recovery, for sure we will say no.

"The main objective here is Le Mans and to be physically prepared, but also I want to be racing. I have the compromise with my team in Formula E, I want to be racing in Formula E as well. It is my second championship I am doing this year. If I am physically fit to do it, I will do it."

Should Lopez be unavailable to race, it is likely that DS Virgin Racing would hand reserve driver Alex Lynn his Formula E debut, racing alongside Sam Bird.
