The drivers are not allowed to test at the Cup venue itself, so that no one gains unfair advantage over anyone else before the race. However, with this resulting in drivers having to resort to testing on non-Cup second-tier circuits without the more modern and expensive safety equipment in place, Keselowski's accident highlights the question of whether this is a safe practice for the series and teams going forward.
As well as testing at Road Atlanta in preparation to competing in the Cup race at Watkins Glen, Jimmie Johnson has also just been "signed up" by his Hendrick Motorsports team mate Dale Earnhardt Jr. as the driver of the JR Motorsports #7 Nationwide Series car for that weekend, as Johnson seeks additional experience at the historic road course venue ahead of the Cup race at the circuit.
It will be Johnson's first Nationwide Series start in three years. Previous occupants of the #7 Chevrolet in Nationwide this season have included Earnhardt Jr. himself, Danica Patrick, Josh Wise, Ron Fellows and Kasey Kahne.
Keselowski by contrast has competed in all but one of the 21 Nationwide races this season, and last weekend won the final series event at Lucas Oil Raceway outside Indianapolis to claim his second victory of the year. He also has one Cup victory to his credit this year - at Kansas in June - but is currently in 21st place in the points standings and out of contention to claim one of the wildcard spots for the Chase based on race wins.
