2013 San Francisco 49ers season
The San Francisco 49ers season was the franchise's 64th season in the National Football League, the 68th overall and the third under the head coach/general manager tandem of Jim Harbaugh and Trent Baalke. This was the 49ers' final season playing their home games at Candlestick Park before moving into Levi's Stadium for the 2014 season.
49ers–Raiders rivalry
The 49ers–Raiders rivalry, more commonly known as the Battle of the Bay, is a professional American football rivalry between the National Football League (NFL)'s San Francisco 49ers and Oakland Raiders. This rivalry is unique in that both teams are members of different conferences within the NFL and have never met in a postseason game, making the rivalry purely geographic, as only 27 miles across San Francisco Bay separate Levi's Stadium, home of the 49ers, and Oakland-Alameda County Coliseum, home of the Raiders. The geographic aspect of the rivalry will end no later than 2020, when the Raiders relocate to Las Vegas, Nevada. Their 2018 Week 9 match up was their last true Battle of the Bay game barring any sudden changes to the NFL's schedule rotation.
