Threefourths of NFL owners must approve a Raiders relocation to Las Vegas.

LAS VEGAS — The Oakland Raiders have filed paperwork to move to Las Vegas.

The NFL and officials in Nevada confirmed Thursday that the team is asking league owners to approve the move, although the team made no immediate comment and a group that wants to keep the team in Oakland vowed it was still in the game and “playing to win.”

Clark County Commission chairman Steve Sisolak made the filing of paperwork public on Twitter and told the Associated Press he spoke with team officials.

Sisolak chairs an elected panel with oversight of the Las Vegas Strip and was part of an 11-member panel appointed by Nevada Gov. Brian Sandoval to study plans for the proposal backed by billionaire casino owner Sheldon Adelson’s company, Las Vegas Sands Corp., to build a domed stadium to lure the Raiders to town.

The proposed 65,000seat domed stadium is expected to cost $1.9 billion, including $750 million in hotel tax revenue, $650 million from Adelson, and $500 million from the Raiders and the NFL. Any relocation to Las Vegas must be approved by three-fourths of NFL team owners.

A statement from an investment group trying to get approval for a new $1.3 billion, 55,000-seat stadium in Oakland said that it would provide additional information to the Raiders and the NFL “so that they can see there is a real and viable option to remain in Oakland.” The investors are anchored by Hall of Famer Ronnie Lott and former quarterback Rodney Peete.
