Forever The Sickest Kids have partnered up with The NFL to record and perform the theme song for their animated series NFL Rush Zone: Season Of The Guardians. The song will be available on iTunes in December.

"We loved the idea of working with NFL and Nickelodeon on this! We had a lot of fun recording the song," singer Jonathan Cook says. Check out the band's new music video for the theme song.

Featuring voices from Detroit Lions Calvin Johnson and Dallas Cowboys De Marcus Ware, NFL Rush Zone: Season Of The Guardians is the first-ever original half-hour animated series jointly developed by a cable network and a major U.S. sports league. NFL Rush Zone: Season Of The Guardians will air regularly Fridays at 9:00pm (EST) on Nicktoons and Saturdays at 7:00am (EST) on NFL Network.

The Dallas, TX foursome will begin recording their third full-length album at the start of 2013, and recently sang the national anthem at the New England Patriots game.
