Obama and NFL Players Team Up for PSA

(AP)  Updated 4:22 p.m. ET

Dallas Cowboys linebacker DeMarcus Ware has played in dozens of important games and hung out with some of the biggest stars in sports.

Still, he was nervous when he met President Barack Obama.

"It's something like no other," Ware said Thursday. "Being able to meet the most important guy in the United States, the guy with the most power, it was unbelievable."

Ware and fellow NFL players Drew Brees and Troy Polamalu filmed a public service announcement with Obama in October that will air during the league's Thanksgiving games.

The 90-second spot shows Obama and the NFL stars playing touch football with local children on the White House lawn. The PSA promotes the league's Play 60 campaign, which encourages physical activity to combat childhood obesity, and the president's community service initiative United We Serve.

Obama wears a Chicago Bears jacket as he plays football with New Orleans Saints quarterback Brees, Pittsburgh Steelers safety Polamalu and Ware.

"I was like 'Ohhhh my God,"' when Obama came out in a Bears pullover," Ware said in a telephone interview. "It was me, Polamalu and Drew Brees there, so you know how we feel about the Chicago Bears. But he's a big Chicago Bears fan. He greeted each one of us, and he knew everything about our teams."

A shorter version of the spot will air throughout the season.
