The JR Motorsports driver was climbing out of his car when the window net beneath his foot slipped and caused him to fall.
The #88 Chevrolet Camaro driver fell headfirst and lay motionless before being attended to by a NASCAR official.
Zilisch was reportedly awake and alert before being transported to a nearby hospital.
“Thank you everybody for reaching out today,” Zilisch wrote on social media.
“I’m out of the hospital and getting better already. Thankfully, CT scans for my head are clear, I just have a broken collarbone.
“Thankful for all the medics for quick attention and grateful it wasn’t any worse.”
Connor Zilisch has been released from the hospital.
