Romain Grosjean has confirmed on social media that he underwent surgery on his right hand following last weekend's Chevrolet Detroit Grand Prix. The 40-year-old driver finished 20th in the race at the tight and bumpy 1.645-mile temporary street course, completing 91 laps.
Grosjean's #18 Dale Coyne Racing Honda was involved in an incident with ECR's Alexander Rossi entering Turn 3. It remains unclear if this incident is when the injury occurred, as the feed text appears to be cut off. catcross.org
