The NFL season has officially started, and the Kansas City Chiefs have their season home opener on Sunday, the same day the nation recognizes the 10th anniversary of the September 11 attacks. And for one game only, some are pushing to change a Chiefs pregame tradition beforem Sunday's game against the Buffalo Bills. It's a controversy that's creating quite a buzz.

The controversy is about whether to sing "home of the brave" or "home of the chiefs" during the National Anthem. To honor those who died on Sept. 11 and in the subsequent wars following the attacks, many feel ending the National Anthem the original way is the right to honor the lost.

VIDEO: FOX 4's Nick Vasos called out on Twitter over issue.

Ten years ago on September 9, 2001 the Chiefs opened the season against the hated Raiders. Two days later terrorists slammed planes into the Twin Towers and Pentagon and shook America to its core. Everything stopped. Including football. When it returned on September 23, most Chiefs fans sang the National Anthem as written.

Now, 10 years later a post on ArrowheadPride.com urges fans to do it one more time on Sunday. Some are on board.

"This is the day to do," said DJ Pittel. "There's a lot of people who not only lost their lives from 9-11 but since then, all service men and women who are over there fighting for our freedom."

Others disagree, citing freedom of speech, adding, 'we can say what we want.'

One fan agreed, sort of.

"We are going to say what the hell we want," said Steve Cook. "We are going to say home of the brave."
    
Which ending will win out??? We'll find out a little before noon Sunday after the pregame tribute to the victims of 9/11.
