The Kansas City Chiefs have asked the NFL to begin an inquiry with the players' association after a union representative held a meeting with the full team late in October without wearing a mask.

The NFLPA representative was in proximity while meeting with the players, according to a source.

The union representative is not subject to the same COVID-19 testing as players and regularly travels among the teams.

The Chiefs have had a handful of players on the NFL's reserve/COVID-19 list this season, including wide receiver Mecole Hardman, who was placed on the list on Wednesday.
