No. 1 JR Motorsports Chevrolet, Sam Mayer disqualified after Xfinity race at Talladega

TALLADEGA, Ala. -- The No. 1 JR Motorsports Chevrolet driven by Sam Mayer was disqualified Saturday evening in post-race inspection after the NASCAR Xfinity Series event at Talladega Superspeedway.

Mayer, who started the race in 12th, took the checkered flag in 16th before the violation. JR Motorsports will appeal the ruling, the team announced in a Monday statement on its social platforms.
