Roger Goodell called any talk of the Oakland Raiders moving to Las Vegas "premature" and discounted most of the available rumors as speculation during his news conference at the Spring League Meeting in Charlotte, North Carolina, on Tuesday.

Goodell also noted that the Las Vegas market would have to be considered "from a gambling standpoint" before the league would consider letting a franchise relocate there.

Mark Davis, who has met with officials in Vegas recently, told reporters on Tuesday at the meetings that the move would "unite Raider Nation."

"I think this has been a very transparent issue," Goodell said about the ongoing struggle for the Raiders to secure a new stadium in Oakland. "I spoke to (Oakland's mayor) last night at 10 o'clock. I'm in touch with her. I told her before, if there are proposals and solutions that she can identify or that we can help them identify. We have given from an ownership standpoint another $100 million, $300 million, to get a stadium built in Oakland. We believe in that market. I know Mark Davis does. But there has to be a solution that's developed. It's not just on us. There has got to be cooperative agreement to try to find that solution. It's been a long time coming. This isn't something that started 12 months ago. This has been a long time that we have been seeking a solution in Oakland and it's time to get to that. We will play our part and I know the Raiders will also."

He added: "The Raiders have been very open about the challenges to get a stadium built. It's not fair to ship all of that responsibility to the Raiders. Public officials, the private sector, the Raiders, the NFL we all have a responsibility. It is a shared responsibility. It's not one person saying it's somebody else's responsibility. We all have to work together to find that solution."

Las Vegas Mayor Carolyn Goodman is confident that the Oakland Raiders will move to Las Vegas unless the deal is mismanaged.

"The Raiders will come if Nevada handles this properly," Goodman told ESPN Radio's Capital Games podcast Tuesday.

Mark Davis met with the Southern Nevada Tourism Infrastructure Committee on April 28 and pledged $500 million toward the construction of a $1.4 billion, 65,000-seat domed stadium.

"Mark Davis has assured us that Las Vegas is not getting played in a Raiders stadium deal," Goodman said. "I know we will have a team."

Goodman said the site under consideration could host the NFL, MLS and UNLV football. She said she is confident that Las Vegas would get an MLS franchise.
