Diffey Named NBC Sports’ Cup Series Play-By-Play Commentator

STAMFORD, Conn. — NBC Sports has announced that veteran motorsports commentator Leigh Diffey will serve as the lead play-by-play voice for its NASCAR Cup Series coverage, beginning with this weekend’s Coke Zero Sugar 400 at Daytona (Fla.) Int’l Speedway on Aug. 24 and continuing through the playoffs and season championship at Phoenix on Nov. 10.

Diffey, who most recently served as NBC Sports’ lead track & field play-by-play commentator at the Paris Olympics, is one of the most prolific voices in motorsports. He has served as NBC Sports’ lead NTT IndyCar Series commentator for more than a decade, including all six of NBC Sports’ Indianapolis 500 broadcasts, and has handled play-by-play for nearly every major motorsport series, including NASCAR, Formula One, IMSA, Supercross and MotoGP.

With Diffey assuming NBC Sports’ Cup Series play-by-play duties, long-time IndyCar commentator Kevin Lee will handle play-by-play for the remainder of NBC Sports’ 2024 NTT IndyCar Series coverage. Lee, whose play-by-play work extends for more than 30 years, has been a host, pit reporter and play-by-play commentator for NBC Sports’ IndyCar coverage since 2009, and has handled play-by-play for a number of IndyCar races this season.

Rick Allen will continue as NBC Sports’ lead NASCAR Xfinity Series play-by-play commentator. 

Allen has called NBC Sports’ NASCAR Cup and Xfinity Series coverage since NBC Sports acquired media rights prior to the 2015 season. Prior to joining NBC Sports, Allen served as a play-by-play announcer for the NASCAR Craftsman Truck Series for more than a decade.
