Chicago Bull’s Zach LaVine is offering his BMW i8 as a prize, but there’s a catch: You have to come up with a flawless NCAA tournament bracket.

“These keys right here, man? They’re all yours. Perfect bracket. I want to see it,” the Bulls star says in an Instagram video. LaVine posted the promotion Sunday night after the selection show.

Athletic retailer The Finish Line partnered up with LaVine for the ultimate basketball experience for consumers, with winning participants walking away with unique prizes including the keys to LaVine’s BMW i8 and a shopping experience with the athlete.

“Teaming up with Zach LaVine for the chance to give away his BMW and provide an exclusive shopping spree showcases the distinctive, close-knit relationships we build with our partners,” said Paul Diehl, senior director of content, social and consumer trends at Finish Line. “We view our partnerships as much more than endorsement deals and unique to the industry. Partnering with Zach in this way provides an opportunity to drive authentic, cultural conversations throughout the tournament.”

At the tournament’s conclusion one fan has the opportunity to receive the keys to LaVine’s BMW, delivered to the winner by the basketball star himself, if they hold a perfect bracket. Additionally, the participant with the highest bracket score will receive a Finish Line shopping experience at the retailer’s Woodfield Mall location in Schaumburg, Ill. with LaVine.

From March 11 – March 15, participants can register online to make their team selections and see the complete list of rules. Stay up-to-date with the Bracket Challenge, including exclusive content with LaVine, by following the retailer’s blog, Twitter and Instagram as well as visiting
