"The NFL's commitment to community and the health and well being of its young fans make them a natural partner for Nickelodeon in the fight against childhood obesity," said Nickelodeon senior VP Public Affairs Jean Margaret Smith. "With this partnership, the network will be able to extend its health and wellness messaging to an even broader reach to families and parents who play a role in helping kids make healthy decisions."

Additional 'Lets Just Play' support will take place in local NFL team markets. Participating teams will promote activity and healthy lifestyles among kids via grassroots events and activities in local communities, and encourage their young fans to sign up for the Go Healthy Challenge, adds the release.

The NFL will also work with Nickelodeon to build awareness around the network's fourth annual Worldwide Day of Play during its pre-season this fall, to distribute "Let's Just Play" branded materials and toolkits through some of its youth programs, and post information on the campaign on http://nflrush.com/, the league's youth website.
