Brown sat out practice Sunday due to an illness, Nate Taylor of The Athletic reports.
Specifics of the illness were not shared, but it doesn't seem like something that will keep Brown out for an extended period. The flashy wideout is set to take on a key role in the Chiefs' passing game this year after signing a one-year deal in March. Though he has the explosiveness to thrive in KC's offense, Brown will need to remain healthy after missing eight contests over the past two years due to injuries.
