PHILADELPHIA (CBS) —  The NFL says they will be donating all profits made from their underdog t-shirts to fund the Philadelphia School District.

“The bottom line is the NFL Shop will also donate 100 percent of the proceeds from this shirt to fund Philadelphia schools,” the NFL said in a statement to CBS3’s Joe Holden.

Last week, Eagles Pro Bowl offensive lineman Lane Johnson decided to promote underdog t-shirts and donate proceeds to fund education in Philadelphia.

On Monday, the NFL’s official Pro Shop account tweeted a photo of a new Eagles Super Bowl LII underdog shirts.

Eagles defensive lineman Chris Long — who was tagged in the tweet — has worn the underdog mask with Johnson after the games.

Long, 32, has also donated all of his game checks towards education funding and he called out the NFL.

“For them to take their idea to make money for themselves, I think it’s a joke,” said Houston Tuminello, Lane Johnson’s manager. “I think it’s low class of them to do that, to take their idea, which Chris and Lane had the idea and want to give it to charity.”

Both Long and Johnson took to Twitter Monday asking the NFL if the profits from the new shirts were going to charity.

Johnson did the same.
