In a statement, ROH and All Elite Wrestling (AEW) boss Tony Khan tweeted: "Sadly, Jamin Pugh has passed away.
"Known to fans as Jay Briscoe, he was a star in ROH for over 20 years, from the first show until today.
"Jay and his brother Mark dominated ROH, reigning as champions to this day. We’ll do whatever we can to support his family. Rest In Peace Jamin."
As reported by Delaware State Police, the fatal crash is said to have occurred in Laurel, Delaware at around 5:30pm EST, with one other person dead in the collision.
Stars from WWE, AEW and beyond have paid tribute to Briscoe, including WWE boss Paul 'Triple H' Levesque.

WWE has been retweeting tributes from its performers, including one from 'SmackDown' star Sami Zayn, who said: "I don’t have the words right now to properly convey my sorrow.
I love Jay [and] Mark Briscoe. Always have.
"I wouldn’t be here without them. I’m very lucky to have shared the ring [and] shared so many laughs with Jay Briscoe and I’m so sad to know neither will happen again. RIP my friend."
