For the Heat, COVID-19 hasn’t been an issue since Derrick Jones Jr., Bam Adebayo and Kendrick Nunn returned after testing positive for the virus in June while in Miami – something each of them subsequently disclosed. (Nunn is now out for other reasons, as detailed below.) But that doesn’t mean there haven’t been some behind-the-scenes glitches. According to a league source briefed by a member of the Heat’s traveling party, at least four Heat players have had some uneasy moments or been ensnared in COVID testing glitches, with the Heat and the players not at fault for any of those.
