Dirk Nowitzki ended speculation regarding his future once and for all Tuesday.

The Mavericks veteran told a packed crowd at American Airlines Center, "This is my last home game," following Dallas' 120-109 victory over Phoenix. 

While many suspected 2018-19 might be Nowitzki's last season, spectators were stunned by his announcement. He appeared to be moved to tears by the fans' reactions.

So what's next for the longtime face of the franchise?

“I want to clear my head. I want to travel. I want to enjoy my family," he told reporters (via ESPN.com), adding that he plans to "stick around the Mavericks somehow."

After spending all 21 seasons with Dallas, he received high praise from owner  Mark Cuban, who has made it clear Nowitzki can have whatever role he wants..

“I promise you that everything you taught us will live on," Cuban said to his star. "I promise you a job for life. I promise you that we’ll retire your number. And I promise you will get the biggest, most badass statue ever."

The 40-year-old big man poured in a season-high 30 points, eight rebounds and three assists against the Suns, and scored the Mavericks first 10 points to open up the game.

The Mavericks won't be headed to the playoffs, as they are 33-48 and sit in 12th in the Western Conference standings. But Nowitzki appears to be on his way to ending an illustrious career in style.

His resume is littered with accomplishments, including a 2007 MVP award, a 2011 NBA championship and 14 All-Star appearances. He is sixth on the NBA's all-time scoring list and entered Tuesday with 31,510 points in his career.

The Mavericks will finish out the regular season against the Spurs on Wednesday at 8 p.m. ET.
