After missing races earlier in 2017 with fractured vertebrae, the German had said after a rollover crash in Monaco that he would undergo scans this week.
“Monaco is checked off for me,” the Sauber driver told Germany’s Sport Bild late on Thursday. “I have no back problems.”
There was similar confirmation on Twitter, with the 22-year-old declaring: “Checks all done. See you in Montreal.”
And the Swiss team Sauber added: “Great news! Medical checks done — ready for the Canadian grand prix”.
