About 1 million people are expected to visit Minneapolis during the week of the Super Bowl. Around 10,000 volunteers have stepped forward in the Twin City for the big game at U.S. Bank Stadium on Feb. 4, which will be preceded by a "massive" 10-day fan festival open to the public. Just four teams are left in the NFL playoffs - the New England Patriots, Jacksonville Jaguars, Minnesota Vikings and Philadelphia Eagles. The New England Patriots have won five Super Bowls, but the Jaguars, Vikings and Eagles have never won a Lombardi trophy. Here are the thirteen NFL teams that have never won a Super Bowl:- Tennessee Titans- Houston Texans- Cincinnati Bengals- Jacksonville Jaguars- Cleveland Browns- Philadelphia Eagles- San Diego Chargers- Minnesota Vikings- Detroit Lions- Arizona Cardinals- Atlanta Falcons- Carolina Panthers- Buffalo Bills
