ALAMEDA, Calif. -- The Oakland Raiders are on the verge of selling out their season tickets for the first time in franchise history, owner Mark Davis said Sunday afternoon.

"We're excited as hell," Davis told ESPN.com. "Again, we've got the greatest fans in the world. The Raider Nation is strong."

The Raiders have signed a one-year lease to remain at the Oakland Alameda Coliseum for the 2016 season and have two one-year options for 2017 and 2018, though the team recently saw its rent triple before the 50-year-old dual-use stadium lost its naming rights from O.co.

Plus, Davis has toured Las Vegas as a potential new home for the franchise, after the Raiders finished third in a three-team race to relocate to the Los Angeles suburb of Carson along with the San Diego Chargers.

The Raiders could still join the Los Angeles Rams in their Inglewood home, should the Chargers decide to remain in San Diego, but momentum is growing in Las Vegas, and Davis is reportedly scheduled to attend a meeting of the Southern Nevada Tourism Infrastructure Committee on Thursday. Davis would not comment on that possibility.

Back in Oakland, excitement is growing for a team that improved to seven wins from three a year ago. The team has a nucleus of young players, such as quarterback Derek Carr, All-Pro outside linebacker/defensive end Khalil Mack and receiver Amari Cooper, recent free-agent signees offensive lineman Kelechi Osemele, outside linebacker Bruce Irvin, cornerback Sean Smith and free safety Reggie Nelson, and re-signed outside linebacker Aldon Smith.

As a result, the Raiders, who spent the 1982 through 1994 seasons in L.A., are in line to have a waiting list for season tickets for the first time in franchise history.

The team has grown its season ticket fan base from 30,000 in 2013 to 37,000 in 2014 to 42,200 last year to just under 50,000 so far this offseason, per Raiders president Marc Badain. That's an increase of nearly 67 percent.

The Coliseum has a capacity of nearly 53,250.
