Sergio Perez says that he would hold on to his drive regardless of a fitness issue and race on even if it meant suffering.
"I hope it really is just a fitness problem for Pascal and nothing worse," Perez told Auto Motor und Sport.
"Hopefully, he will soon be fit again."
Wehrlein's troubles reminded the Mexican of a similar problem he encountered in his first season of Formula 1 racing in 2011 when he was also a Sauber driver.
Perez suffered a huge crash during the season and was forced to sit out the following race despite the fac t that he was determined to drive.
"I respect Pascal's decision," Perez said.
"But I would not leave my car to anyone. Even if you're suffering in the car, you try to get the best out of it.
"After my accident I had to suffer until the summer break, which was four or five races."
