Al Davis may be dead, but the Oakland Raiders' wanderlust persists.

Raiders owner Mark Davis (Al's son) was among three team executives who met with San Antonio officials earlier this month to discuss a possible franchise relocation, according to a report Tuesday by MySanAntonio.com. The Raiders' lease with the city of Oakland to play in O.co Coliseum expires following this season.

San Antonio already has a stadium built, though the 21-year old Alamodome would likely need significant upgrades before being ready to host an NFL team. Texas San-Antonio and the arena football San Antonio Talons play their home games in the building, which also hosts the annual Alamo Bowl.

Any proposed franchise move would need to pass an league-wide ownership vote, with 24 of 32 required for approval. NFL spokesman Greg Aiello largely declined comment about the Raiders possible moving to San Antonio.

"We don't have any information about (Davis' meeting in San Antonio), so there is no reason for us to comment," Aiello told MySanAntonio. "We have received no applications from any of our teams to relocate at this point, so there is nothing for us to respond to."

San Antonio has often been used as leverage for NFL teams considering relocating, including the New Orleans Saints, the Minnesota Vikings, the Arizona Cardinals and the San Diego Chargers. The Saints played several home games in San Antonio in 2005 after Hurricane Katrina had rendered the Louisiana (now Mercedes Benz) Superdome unplayable.

The Raiders have moved twice in their history, to Los Angeles in 1982 and then back to Oakland in 1995. Mercurial team owner Al Davis died in 2011.
