The president of the Baltimore Ravens told fans and sponsors in a letter that its game attendance during the 2017 season has been hurt by players' national anthem protests.

Team President Dick Cass made the announcement this week, the Wall Street Journal reported.

On "Fox & Friends," Pete Hegseth said the Ravens' attendance at M&T Bank Stadium declined this year despite the fact the team is second in their division behind the Pittsburgh Steelers.

He also said that the protest by about a dozen players at the Ravens' September game in London could be chiefly to blame.

Players on both the Ravens and the opposing Jacksonville Jaguars were criticized for protesting during the "Star-Spangled Banner" but standing up for Britain's "God Save the Queen."

The demonstrations "became an emotional and divisive issue," Cass wrote, according to The Journal. "We know that hurt some of you."

He said that the higher amount of empty seats is "noticeable" during the games.

The Journal reported that Cass' letter contradicts the league office, which holds that the protests have had no significant effect on game attendance changes.
