 By virtue of winning Super Bowl XLVII, the Ravens were scheduled to host the Kickoff Game on Thursday, September 5, 2013; however, due to a scheduling conflict with the Baltimore Orioles (with whom they share a parking lot) and the NFL's refusal to move the game to a different night, the Baltimore Ravens were the first Super Bowl Champion in 10 years not to host the following year's Kickoff Game.The 2013 Kickoff Game was played at Sports Authority Field at Mile High when the Ravens visited the Denver Broncos.After losing linebacker Ray Lewis and center Matt Birk to retirement, the Ravens' roster underwent significant changes throughout the 2013 offseason.
