The news is notable seeing as the Denver Broncos will play three games on NBC in 2013—with a Sept. 5 Thursday night season opener against Baltimore, an Oct. 20 Sunday night showdown in Indianapolis and a Nov. 24 Sunday evening spot in New England.
Underwood, the American Idol Season 4 winner and six-time Grammy Award winner, will still perform Hill's popular Waiting All Day for Sunday Night piece, but the song will be tweaked to fit Underwood's style, according to NBC.
Last fall, the intro video included appearances from more than twelve different players, with no Broncos making the cut. With Denver scheduled to play three times on NBC this fall, it wouldn't be surprising to see a Bronco included in the intro this year (keep an eye out for Von Miller and Peyton Manning).
In 2007, Underwood co-hosted NBC's Saturday Night Live with Manning, who was a member of the Indianapolis Colts at the time. Underwood also performed the national anthem at Super Bowl XLIV in 2010, a game in which Manning's Colts fell to the New Orleans Saints, 31-17.
