Alfa Romeo driver Zhou Guanyu will be behind the wheel for the Austrian Grand Prix this weekend ... just days after surviving a horrifying crash at Silverstone.
"Finished the final medical check, all good to go!" Guanyu tweeted Thursday morning ... sharing a pic with FIA staffers.
"Thanks to all of the people who supported me during this time, means the world. u2764ufe0f #AustrianGP LET'S GO! ud83dudcaaud83cudffc"
The news is pretty incredible ... especially considering how serious the scene was during the first lap of the British Grand Prix.
