Pittsburgh Steelers offensive lineman and decorated Army veteran Alejandro Villanueva became an instant hero to many fans around the National Football League when he became the lone player on the Pittsburgh Steelers to stand for the national anthem before Sunday's game against the Chicago Bears. And those fans are responding to Villanueva's act with their wallets.

On Fanatics.com, sales of Villanueva's jersey skyrocketed, launching up to the third highest-seller in Pittsburgh Steelers jersey as of just before 8 PM Eastern time, behind only a custom Steelers jersey and Antonio Brown's jersey. Villanueva's jersey also jumped into the top sellers around the league, and as of 7:45 PM EST trailed only Marshawn Lynch, Derek Carr, Carson Wentz, Brown, and Aaron Rodgers in sales.

After a loss on the road, the Steelers will travel to Baltimore to face the Ravens before returning home to host the Jacksonville Jaguars. When they come back to Pittsburgh, there figure to be many more No. 78 jerseys in the crowd than ever before.
