49ers president Jed York was asked about the possibility of sharing a stadium with the Oakland Raiders in the Bay Area during an interview with KNBR. "Sharing a stadium at a very high level makes a lot of sense," said York. "We've carved out in our deal that we can potentially have two stadiums in Santa Clara." York continued and talked about the possibility of building a stadium where the Oakland Coliseum currently exists if the 49ers are unable to successfully build their stadium in Santa Clara. "If we could do a joint stadium in Oakland as an alternative, it is something that I would at least explore." Source: RealGM.com
