The Heat didn't offer official comment on either report.
The incident complicates what already was a hard stretch for Waiters, who missed time during preseason for what the team said were personal reasons.
After an incident in which Waiters complained about a lack of playing time in the preseason, he was suspended for the first game of the regular season. The 27-year-old missed Thursday's game against the Phoenix Suns with what the Heat labeled as a "stomachache".
It was confirmed by sports journalist Andy Slater after the plane landed, adding in his reporting that Waiters suffered a seizure upon being awakened. Then he was suspended by the Heat for the October 23 season opener for "conduct detrimental to the team" after he criticized his role on social media.
The mother of Waiters, Monique Brown, went to social media on Saturday morning and posted a message on her Instagram story: "Please don't Believe the rumors the media will report fake news to get clicks and likes. smh none of that mess is true!" Through nine games, he has only twice been active and has not been in uniform and on the bench. Waiters will also miss out on a $1.2 million games bonus. He is due $24 million this season and next.
