An online fundraiser has been set up to help the family of a Lincoln man critically injured during an accident at a racetrack Saturday.

During a race at Eagle Raceway, one of the race car's acceleration throttles got stuck and the car went airborne, striking a row of vehicles and injuring three people. One of those people, Justin Vanderharr, a father of two, suffered severe head injuries. 

Close friends of Vanderharr set up a GoFundMe to help Vanderharr's family with medical expenses and other costs associated with the accident. 

Friends say Vanderharr has spent the past few days in a medically induced coma, but is showing small signs of improvement. 

"At about four o'clock this morning before I left ICU he actually squeezed my hand a little bit so, for me, that was pretty big," Adam Gullion, a close friend of Vanderharr, told Channel 8 Eyewitness News on Monday. "I introduce him to people as my brother and likewise for him... so that hand squeeze was a pretty big deal for me."
