San Francisco 49ers
The team was founded in 1946 as a charter member of the All-America Football Conference (AAFC) and joined the NFL in 1949 when the leagues merged. The 49ers were the first major league professional sports franchise based in San Francisco. The name "49ers" comes from the prospectors who arrived in Northern California in the 1849 Gold Rush. The team is legally and corporately registered as the San Francisco Forty Niners. The team began play at Kezar Stadium in San Francisco before moving across town to Candlestick Park in 1970 and then to Levi's Stadium in Santa Clara in 2014.
2019 Raiders season
The team's 24-season tenure in Oakland, California, where it played as the Oakland Raiders (the second time in the team's history it has resided in Oakland) from 1995 to 2018, is expected to end during the 2019 offseason. The team has indicated it will not seek a renewal at the Oakland–Alameda County Coliseum, which no longer meets NFL standards and itself is seeking financial damages against the NFL and the Raiders. The team has long-term plans to relocate to a new stadium in Paradise, Nevada, a suburb of Las Vegas, a stadium that is not expected to be ready for use until 2020, and no other NFL-caliber stadiums exist in the state of Nevada. The team's home city, and thus the full team branding, will depend upon the stadium with which the Raiders sign a temporary lease for the 2019 season. As of January 2019, Oracle Park in San Francisco is believed to be the most likely home for the Raiders for 2019, which would return the team to San Francisco for the first time since its first two seasons; that venue is the only one that all parties (the league, venue and team) have acknowledged conversations regarding a home. Other possibilities being discussed include San Diego, California (SDCCU Stadium), Whitney, Nevada (Sam Boyd Stadium) or Reno, Nevada (Mackay Stadium), with Raiders management outright rejecting sharing Levi's Stadium in Santa Clara with the 49ers due to their heated rivalry. Arizona Stadium in Tucson entered the conversation in January 2019, and the Raiders have acknowledged considering that city, according to Ali Farhang, an attorney lobbying to bring the Raiders to Tucson.
