MIAMI (AP) — Dirk Nowitzki says Dwyane Wade and LeBron James were "a little childish, a little ignorant" in a video in which they appear to mock the Mavericks star's recent sinus infection.

The video taken by the CBS affiliate in Dallas-Fort Worth shows Wade walking alongside James following a shootaround the morning of Game 4 of the NBA finals. Wade coughs, then says, "Did you hear me cough? Think I'm sick."

At news conferences Saturday, Wade said it was a real cough and he made a joke of it because cameras were around. He also noted that Nowitzki's name was never mentioned.

James called it "a non-issue."
