The NFL has agreed to stop marketing its fantasy football product to children under the age of 13, according to the Associated Press.

The league had pushed its NFL Rush Fantasy game on kids, even offering an elementary school curriculum to help promote the game which offered cash and video game prizes.

Anti-gambling and anti-commercialism groups have criticized the game, saying it could promote gambling and addictive behavior.

"We are pleased that the NFL has agreed to make these changes, and young children will no longer have a financial stake in the outcome of its games," said Josh Golin, executive director of the Campaign for a Commercial-Free Childhood. "It is also good news for parents that the league will no longer enlist teachers and schools in an effort to get children into the habit of playing fantasy sports."

The league has promised to discontinue the school programs, and not market to children aged 6-12 in their schools in the future.
