Officials overseeing the O.co Coliseum approved short-term leases Monday for both teams.
The Raiders' lease was extended through the end of the 2014-15 season. The A's were signed through December 2015.
The Joint Powers Authority says the Raiders will pay $400,000 in 2014. The A's will pay $1.75 million each of the two years of the extension.
The lease deals now go before Oakland and Alameda County officials for approval.
The coliseum authority says it plans to continue working on long-term deals to retain both teams. The A's have made no secret of their desire to leave for San Jose.
