Meek Mill and Jay-Z’s Roc Nation are collaborating with streaming service DAZN on a documentary about heavyweight fighters Anthony Joshua and Andy Ruiz Jr.

40 Days: Joshua-Ruiz will be presented as multi-part short-form episodes and premiere May 21 on Mill’s YouTube channel. Episodes will debut each Tuesday and Thursday in the two weeks leading up to the fight. A special final edition of 40 Days will premiere on NBC Sports Network and several regional sports networks prior to the June 1 showdown.

“DAZN has created a program that explores a fighter’s heart and soul,” stated Meek Mill. “They tell the story of what makes a true champion. I love being part of a project that tells of their grit, sacrifices and dedication outside the gym. It’s those things that show true character and should be lauded just as much as the knockouts in the ring.”

“The purpose of 40 DAYS is to pair globally famous boxers with compelling storytellers to give fight fans an original look at the eight weeks leading up to a fight,” says Jamie Horowitz, EVP Content, DAZN North America. “It’s a series which is meant to let creative people be creative. We are excited to have Meek Mill tell the story of Anthony Joshua’s first fight in America through his unique lens.”

DAZN and Joshua’s promoter Matchroom Boxing USA President Eddie Hearn will also serve as producers on the series along with Patrick Reardon of Roc Nation. As part of the fight week activities, Meek Mill, Roc Nation and DAZN will host an exclusive 40 DAYS: JOSHUA-RUIZ world premiere event in New York City for media and influencers.

According to Roc Nation, the 40 DAYS documentary title is derived from the grueling preparation for a prizefight that requires roughly eight weeks of Monday-Friday intense training. The first edition of 40 DAYS captured the build-up to the Cinco de Mayo weekend matchup between Canelo Alvarez and Daniel Jacobs, which debuted globally on April 23.
