However, Mavericks owner Mark Cuban said he tried to talk NBA Commissioner Adam Silver into letting the former Dallas Cowboys quarterback find his way onto the hardwood.
"I told him what I was going to do and said, 'Fine me if you don't like it,'" he said, according to ESPN.com's Todd Archer.
Silver ultimately nixed the idea by telling Cuban the NBA wouldn't honor a contract if Romo signed with the Mavericks.
Although Romo wasn't allowed to log official playing time in the Mavericks' home finale, he did participate in pregame festivities and layup lines before the game officially got underway, as the team's official Twitter account documented:
He also addressed the Dallas faithful prior to tipoff.
"This is an honor I could never have dreamed of," Romo said, per Archer. "It's a little embarrassing, but I tell you what I'm very lucky. Thank you, Dallas. I love you."
Romo, 36, retired from the NFL on April 4 following 13 seasons with the Cowboys. He's now pursuing a new career with CBS Sports as its lead football announcer alongside Jim Nantz.
