The National Football League has declared that 'football is gay' in a promotional video released on Pride Day, after Las Vegas Raiders defensive end Carl Nassib became the league's first openly gay player.

The video released on Monday shows simple white text against a black background, as snare drums play in the background and people are heard cheering as the text declares 'Football is gay.'

'Football is lesbian. Football is beautiful. Football is queer. Football is life. Football is exciting. Football is culture. Football is transgender. Football is heart. Football is power. Football is tough,' the video continues.

'Football is bisexual. Football is strong. Football is freedom. Football is American. Football is accepting. Football is everything. Football is for everyone,' the proclamation adds.
