Denver Broncos linebacker Brandon Marshall says he plans to meet with Denver police chief Robert White on Tuesday.
Marshall kneeled when the national anthem was played in the team's season opening game against the Carolina Panthers last Thursday.
He was showing support to San Francisco quarterback Colin Kaepernick. Kapernick has chosen not stand for the national anthem before games as a protest to police violence and racial inequality in the United States.
Kaepernick says he will continue his protest and almost a dozen other NFL players have joined in the protest.
Marshall has lost two endorsement deals because of his protest.
