Fantasy: Fill out your In-Season Challenge bracket for a chance to win $1 million

Are you having withdrawals from March Madness? Or maybe that bracket in March didn't go too well for you, and you need a do-over. Whatever the case, NASCAR's In-Season Challenge Bracket Game is here to feed your need for filling out brackets. And here's the kicker: if you fill out a perfect bracket with us, you'll be eligible to win $1 million. All you have to do is register for a NASCAR.com account (it's free), join the In-Season Challenge Bracket Game and fill out your bracket by 6:55 p.m. ET on Saturday, June 28, before the Quaker State 400 at EchoPark Speedway (formerly Atlanta Motor Speedway). That race will kick off TNT Sports' return to NASCAR and will mark the beginning of the In-Season Challenge, a five-race tournament with head-to-head driver matchups where the field of eligible drivers will be whittled down until a tournament champion is crowned on July 27 at Indianapolis Motor Speedway. The tracks for the In-Season Challenge include EchoPark Speedway (formerly Atlanta), the Chicago Street Course, Sonoma Raceway, Dover Motor Speedway and Indianapolis. The field of eligible drivers will decrease from 32 to 16 to 8 to 4 and then finally to the final two at Indy. But just like the NCAA Tournament, you'll need to make all your picks before Saturday's race in order to have a chance at the $1 million. The good news is that your single entry will not only get you into the perfect bracket game, but it will also make you eligible for top prizes in the fantasy game. For the fantasy game, points will be awarded for each correct pick, with 10 points for each correct pick in Round 1, 20 points for Round 2, 40 points for Round 3, 80 points for Round 4 and 160 points for the Final Round. The top three point scorers in the fantasy game will be eligible for cash prizes topping out at $10,000. If you want some help filling out your bracket, check out our driver capsules, where we break down the strengths and weaknesses of drivers seeded from No. 1 to No. 32. Plus, we'll have plenty of other In-Season Challenge content rolling out throughout the week, including Neil Paine's Bracket Buster picks on Thursday. If you don't have time for all that, there will be a Bracket Auto Fill option for those who want to throw caution to the wind and just ride with a computer-generated bracket. And of course, there will be a chance for you to share your picks on social media where the trash-talk can truly begin. So don't be left out of the fun! Fill out your bracket today.
