The Mavericks announced Friday July 12 that the deal was done.
Porzingis and the Mavericks agreed earlier this month on a USD 158 million, five-year maximum contract -- the last season being a player option. That will pair the Latvian standout with fellow young Euro star Luka Dončic, the 20-year-old from Slovenia who was the NBA's Rookie of the Year last season when he averaged 21.2 points.
Porzingis, who turns 24 on August 2, sat out all of last season after tearing the anterior cruciate ligament in his left knee on February 6, 2018, in what turned out to be his last game for the New York Knicks. The injury happened not long after Porzingis was named an All-Star.
In 186 games over three seasons with the Knicks after being the fourth overall pick in the 2015 draft, Porzingis averaged 17.8 points and 7.1 rebounds. He averaged 22.7 points through 48 games in 2017-18 before the injury that has since kept him out of NBA games.
