Audi has confirmed that Benoit Treluyer will miss this weekend's FIA World Endurance Championship round at the Autodromo Hermanos Rodriguez in Mexico City through injury.
Treluyer was forced to miss the last race at the Nurburgring after suffering a minor spinal injury while training, but aimed to be fit to race for the WEC's first visit to Mexico.
Treluyer took part in practice on Friday and said it was a "good opportunity to get used to the car again", but will be rested for the remainder of the weekend.
"In the race, Benoit needs to be absolutely fit," Audi head of motorsport Dr. Wolfgang Ullrich said.
"In agreement with our team physician, we have decided to give Ben more time to recover and to build up his fitness again in order to be one hundred percent fit for the 6-hour race in Austin in two weeks’ time."
Just as it was at the Nurburgring, the no. 7 Audi R18 will be shared by Marcel Fassler and Andre Lotterer for qualifying and the race on Saturday.
Treluyer's withdrawal follows that of Toyota LMP1 driver Anthony Davidson, who is also being rested after sustaining an injury while testing last month.
