LONDON (Reuters) - Sauber driver Pascal Wehrlein will miss Formula One's opening pre-season test in Barcelona at the end of February due to a lingering back problem, the German said on Friday.
"I have to skip the first winter test due to medical advice because of a BACK issue. I feel sorry for the team but we'll come back stronger," the 22-year-old said on Twitter.
