ANALYSIS: According to the article, this is the highest count of absences so far in the 2020-21 season. The league expects those refs to be back by the start of the 2021 NBA Playoffs. The story also notes that because referees fly commercially, and not on charters like teams, they have a greater risk of outside exposure.
