He died from his injuries late Sunday. He was 27.
Clauson’s family released this statement early Monday morning:
Last night, the 7th of August, we said goodbye to our son, my fiancé, our friend, Bryan Clauson. He was surrounded by family and friends and we were grateful that we could experience his final moments with him.
Our Bryan fought to the end with the same desire that he demonstrated behind the wheel of all the various race cars he would park in victory lane. However, we were more proud of our Bryan that took a moment to make a young fans day, or demonstrated his uncommon kindness and appreciation toward his friends, family and fans.
We would like to thank everybody who has shown their concern toward us and kept us in their prayers. We will never be able to truly thank you. We would also like to thank the staff at Bryan Medical Center who stood and fought with our Bryan since he arrived here early yesterday morning.
We know that our Bryan is also your Bryan and that you would like to participate in honoring him. A service will be held at the Indianapolis Motor Speedway at a date and time to be announced soon. In lieu of flowers, or to make a donation, people may direct their contributions to the USAC Benevolent Fund website at http://usacbf.org/cash-donation/ or checks can be made out to the USAC Benevolent Foundation in the name of Bryan Clauson. The address is 124 E Northfield Drive, Suite F #129, Brownsburg, IN 46112.
Thank you for being a part of our Bryan’s life.
2. Tony Stewart was a Team Owner for Clauson
NASCAR driver and team owner Tony Stewart was a longtime team owner for Clauson.
Stewart himself was a former USAC Midget Car champion, winning the series in 1994 and 1995.
Stewart heard about the crash and told NASCAR.com from Watkins Glen on Sunday:
Yeah, terrible thoughts. It’s a tragedy. That kid drove for us for a long time and did a great job and never went anywhere, I don’t care what happened, no matter how bad his day was, he always found a way to smile with it. Him and Lauren being engaged, the kid had such a bright future, and it’s just … it was hard to start the day today in the car. It sucks when it’s anybody in racing. It’s hard when you lose them, but it’s even worse when they’re somebody as close to you as Bryan was.
A number of drivers, team owners and others associated with racing took to Twitter to share their condolences.
