Pittsburgh Steelers' Alejandro Villanueva, who has the best-selling jersey in the NFL, is donating the proceeds to United Service Organization Organiations Inc. and other military groups.

ESPN's Adam Schefter made the announcement on Twitter.

Villanueva is riding a wave of popularity after being the only member of his team to stand on the field during the national anthem ahead of Sunday's game against the Chicago bears. He served three tours in Afghanistan as an Army Ranger and earned a bronze star for valor.

The Steelers opted to stay in the locker room in response to President Donald Trump's criticism of players who protest racial inequality by kneeling during the anthem.

Villanueva consulted coach Mike Tomlin and Ben Roethlisberger before making his decision to stand in the front of the tunnel.

Villanueva later said he intended to stay in the tunnel where nobody could see him. Few of his teammates knew about his plan because he only told team leadership.

He later said the plan was "butchered" and apologized.
