The Oakland Raiders traded up in the fourth round to select Connor Cook out of Michigan State.

Oakland gave up the No. 114 and No. 154 overall selection to move to 100th overall.

Before the start of the fourth round, multiple teams had shown interest in trading up for the first pick of the round.

Cook will compete with Matt McGloin to be Derek Carr's backup.

Mark Davis said Thursday that he wants to move the Raiders to Las Vegas and pledged $500 million toward the building of a proposed $1.4 billion domed stadium in the city.

Davis didn't promise to move the Raiders to Las Vegas, but his pledge to contribute $500 million to a potential stadium is a significant development.

The owner made the comments during a meeting of the Southern Nevada Tourism Infrastructure Committee at UNLV.

The NFL has long shunned Las Vegas, refusing its TV ads and telling players not to make appearances at casinos. However, Davis said he believes owners will approve the move if the stadium is built.

"If we give them an offer they can't refuse, and that's what we're talking about now, I don't see a problem," Davis said.

The Raiders are on the verge selling out their season tickets for the first time in franchise history, owner Mark Davis said on 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,

Aldon Smith has re-signed with the Oakland Raiders.

Smith is currently serving a yearlong suspension that was handed down in November when he violated the NFL's substance-abuse policy, received a two-year contract.

The No. 7 overall pick of the 2011 draft out of Missouri by the San Francisco 49ers, Smith spent time in rehab in 2013 and served a nine-game suspension in 2014.

"I think in his heart he's a good young man," Raiders coach Jack Del Rio said of Smith during the NFL owners meetings in March. "I feel like all of us, we can all work to be better, and in my time around him, I enjoyed being around him. Good teammate. Good to be around. He's a good kid."
