The Sauber driver had to miss the start of the 2017 season after injuring his back in a crash during the ‘race of champions’ winter event.
Now, in Monaco, Wehrlein was once again able to walk away from a similar rollover crash, before slamming McLaren fill-in Jenson Button for the “stupid” overtaking attempt.
The German broadcaster RTL reports that Wehrlein experienced back pain in the aftermath.
“Yes, I’ll have to do a scan next week,” the 22-year-old confirmed.
Wehrlein is also quoted as saying by Brazil’s Globo: “I hope to be ok.
“I hit my head on the barrier again, so I will have to do a new CT scan of my back. We’ll see.
“It seems ok, but since I had this injury, I’m not sure,” he added.
