LOUDON, N.H. — NASCAR is paying tribute to crew chief Nick Harrison, who died overnight after Saturday’s Xfinity Series race.

NASCAR announced Harrison’s death during the driver’s meeting before Sunday’s race at New Hampshire Motor Speedway and honored him with a pre-race moment of silence. No details were given.

The 37-year-old Harrison was crew chief for Justin Haley, who finished in 13th place Saturday. In Harrison’s first season with Kaulig Racing, Haley had two top-five finishes and finished 12 times in the top 10.

“Not just a crew chief, but a friend to everyone who knew him,” Haley wrote on Twitter. “I, and everyone at Kaulig Racing are devastated. He will be greatly missed.”

According to NASCAR, Harrison was a veteran crew chief with all three NASCAR national series since 2006. His teams won five Xfinity Series races with drivers Austin Dillon, Paul Menard and Kurt Busch, who were all driving Sunday.

“We all lost a friend last night. We love you Nick Harrison. You were a leader, and a great friend to all,” Busch posted on Twitter. “Nick really helped me rebuild my career when I was at a low point. RIP.”
