Dallas Mavericks superstar Luka Doncic has agreed to sign a landmark five-year, $207 million supermax rookie extension, agent Bill Duffy of BDA Sports told ESPN on Monday.

Doncic, one of the most accomplished players in NBA history at 22 years old and rapidly evolving into the future face of the league, becomes the first player eligible for the designated rookie max extension upon signing because he's already twice been voted first-team All-NBA.

According to ESPN, Mavericks owner Mark Cuban, general manager Nico Harrison, coach Jason Kidd, assistant general manager Michael Finley, special adviser Dirk Nowitzki and director of player health and performance Casey Smith all made the trip to Slovenia.
