The German suffered a back injury at the Race of Champions earlier this year and has decided to sit out of the test in Barcelona at the end of the month after undergoing medical tests.
“I feel sorry for the team, but we’ll come back stronger,” Wehrlein said on Twitter.
Sauber are yet to confirm Wehrlein’s replacement. It could be that they decide to only run Wehrlein’s teammate, Marcus Ericsson, in the first test, but Ferrari’s Antonio Giovinazzi is understood to be being considered.
The GP2 runner up took his first spin in an F1 car earlier this month after being confirmed as Ferrari’s third driver.
