Dirk Nowitzki said that Dwyane Wade and LeBron James were "a little childish, a little ignorant" in a video that appears to show them mocking the Mavericks star's recent illness.
Wade and James blamed the media for trying to make a big deal out of it.
The video taken by the CBS affiliate in Dallas-Fort Worth shows Wade walking alongside James following a shootaround the morning of Game 5 of the NBA Finals. Wade coughs, then says, "Did you hear me cough? Think I'm sick."
Nowitzki was coughing and sniffling throughout Game 4 because of a sinus infection that also left him with a 101-degree fever.
"We never said Dirk's name," Wade said. The video clip runs 26 seconds. After Wade coughs, he and James laugh and tug their collars over their nose and mouth, as Nowitzki did during his interview following Game 4.
