Dallas Mavericks center Kristaps Porzingis is the subject of trade rumors as he deals with his latest injury setback. Porzingis is expected to return Saturday night at Brooklyn after missing three games with back stiffness. The 7-foot-3 Latvian brushed off the trade talk. The 25-year-old Porzingis came to Dallas in early 2019 as the centerpiece of a blockbuster deal with the New York Knicks. He has missed 32 of 106 games over two regular seasons with the Mavericks, who acquired him with the hope of making him the sidekick to star point guard Luka Doncic.
