San Francisco 49ers
The San Francisco 49ers are a professional American football team located in the San Francisco Bay Area. They compete in the National Football League (NFL) as a member of the league's National Football Conference (NFC) West division. The team currently plays its home games at Levi's Stadium in Santa Clara, California, located southeast of San Francisco in the heart of Silicon Valley. Since 1988, the 49ers have been headquartered in Santa Clara.
Multi-purpose stadium
The Miami Marlins, which changed their name from the original Florida Marlins in November 2011, moved to Marlins Park, a new retractable-roof stadium in Miami, in 2012. Sun Life Stadium (now Hard Rock Stadium) was then renovated to eliminate its baseball functionality, making it a football-only stadium. With the Marlins' relocation, the Oakland Athletics are the last team in the U.S. still sharing a stadium with an NFL team (the Oakland Raiders), the Oakland Coliseum. This arrangement will end once the Raiders move to Las Vegas (most likely in 2020), after which each NFL and MLB franchise will have its own stadium. The Athletics are currently seeking a new home; they are currently exploring plans to build Oakland Ballpark. Before announcing their upcoming move to Las Vegas, the Raiders suggested a move back to Los Angeles, where they played from 1982 to 1994, and also actively explored a move to the Alamodome in San Antonio; other parties suggested that the Raiders share the new Levi's Stadium in Santa Clara with the 49ers.
