Las Vegas Motor Speedway will host the first playoff race for the Monster Energy NASCAR Cup Series next season, and the race will have a new sponsor for the 2018 postseason.
According to Motorsport, South Point Hotel, Casino and Spa will sponsor the race, and they agreed to a multi-year deal with the speedway.
The race will take place in September, and LVMS president Chris Powell said he's proud to announce South Point as the new sponsor.
"(Casino owner) Michael Gaughan has been a great friend to Las Vegas Motor Speedway for decades, and we're infinitely proud to have South Point as a major part of our first Monster Energy NASCAR Cup Series Playoff race and our inaugural fall tripleheader weekend," Powell said.
"The South Point 400 will showcase the best drivers in the world at one of the most fan-friendly and dynamic tracks in the country over the course of a weekend that fans will long remember. The coming year will be an historic one for our speedway, and we're ecstatic about what the future holds."
Martin Truex Jr. won the race at Las Vegas in 2017, and it was the first of his eight wins en route to his first championship.
The race in Las Vegas was held in March of 2017, and it was the third race of the year for the Cup Series. Now, it will replace Chicagoland as the first race of the postseason.
