UPDATE: Saturday's NASCAR Daytona 400 earned a 2.7 rating and 4.4 million viewers on NBC, down 16% in ratings and 18% in viewership from last year (3.2, 5.4M) and down 21% and 22% respectively from 2016 (3.4, 5.7M).
The 2.7 rating is tied as the lowest on record for the race, excluding rainouts (dates back to 1997). It matched 2015, when the race did not start until after 11 PM ET and was overshadowed by the Women's World Cup final. Even including rainouts, it was the second-lowest rating on record ahead of a postponed 2014 race on TNT (2.4).
Erik Jones' win also ranked as the least-watched at Daytona since the above-mentioned 2015 race (4.0M).
Despite the lower numbers, NASCAR was still the top non-World Cup sporting event of the weekend. It comfortably topped FOX Major League Baseball coverage head-to-head (1.4, 2.2M).
