Politics has been called a blood sport, so it's not too much of a stretch for Washington to be hosting its first Ultimate Fighting Championship on Saturday.
Still, mixed martial arts was once a sport that Sen. John McCain, R-Arizona, tried to get banned because of its violent nature.
Today, with safer guidelines in place, the sport is thriving and has a huge following in the U.S. and a growing audience globally.
Saturday's event is being held at Verizon Center with 10 bouts on the card.
UFC president Dana White tells CNN that Washington is ripe for the sport.
"Anytime we go into a new market, whether it's here in the United States or somewhere else around the world, it's always exciting... I expect D.C. to be very good for us," said White. "This is the most exciting live sporting event you will see in all of sports."
"I don't care what color you are, what country you come from, or what language you speak," White said, "We're all human beings. Fighting is in our DNA. We get it and we like it. This thing works everywhere."
The Green Bay Packers say they'll be the first team in the NFL to screen fans with hand-held metal detecting wands when the team hosts the Denver Broncos this Sunday.
The wands, which will replace pat-downs as the primary method to screen people as they enter Lambeau Field, are similar to those used by the Transportation Security Administration at airports around the country.
The measure is being implemented at the recommendation of the NFL, team representative Aaron Popkey said.
The Packers' director of security and risk management, Doug Collins, said the procedures will increase the safety of fans at the stadium. He advises fans to arrive at Lambeau earlier than in the past, since it may take more time for Green Bay police officers to perform the enhanced inspections at the gate.
Pat-downs may still take place if officers notice anything suspicious, Popkey said.
