Dale Jr. boosts IndyCar TV Rating

NASCAR star Dale Jr. boosted IndyCar's TV rating 25%

NBCSN earned a 0.22 rating and 202,000 viewers for Saturday's IndyCar iRacing event at Michigan, which featured NASCAR star Dale Earnhardt Jr.

That's up 25% from IndyCar's iRacing TV debut the prior week at Barber Motorsports Park.

Dale Jr. will not race in this weekend's IndyCar iRace at Motegi, Japan. It's likely NASCAR put the kibosh on him helping IndyCar's TV ratings.
