The Oakland Raiders will be unable to extend Khalil Mack until 2018.

The Raiders signed Derek Carr to a contract extension earlier this month and followed it up with a five-year, $56 million extension with Gabe Jackson.

Mack's contract will be too big for the Raiders to fit under their cap.

The Oakland Raiders have signed Gabe Jackson to a five-year, $56 million contract extension.

Jackson's annual salary of $11.2 million is the third highest in the NFL amongst guards.

Jackson was taken with the No. 81 pick of the 2014 NFL Draft following the Khalil Mack and Derek Carr selections.

Jackson was a Pro Bowl alternate in 2016.

Derek Carr is excited to play with Marshawn Lynch and says he'll gladly hand the ball to the bruiser near the goal line.

"My No. 1 goal is that I'm going to make sure that I give everything I have to this organization," Carr said.

"There's no pressure, there's no, you know, we'll be on the 1-yard line and I won't give it to Marshawn -- I'll throw it. There's none of that stuff. I don't care about the stats. That's not my No. 1 objective. I don't care if I throw 10 touchdowns next year. If we win every game, that's all I care about."

Derek Carr and the Oakland Raiders have finalized a five-year, $125 million extension.

Carr, 26, is now under contract through 2022. His extension's average salary of $25 million will make him the NFL's highest-paid player in terms of new money average.

Carr's deal could potentially be backloaded until the Raiders move to Las Vegas; there is no state tax in Nevada, whereas California's tax rate is 13.3 percent. Carr could save hundreds of thousands of dollars, if not millions.

Carr passed for 3,937 yards and 28 touchdowns with just six interceptions last season.

Derek Carr tweeted Thursday that he has finalized a five-year extension with the Oakland Raiders that sources indicate is worth $125 million.

Carr's new deal, which carries an average salary of $25 million, will make him the NFL's highest-paid player in terms of new money average.

He suffered a broken fibula in Week 16 and missed Oakland's playoff loss to the Houston Texans, but he has been a full participant in the team's offseason activities.

Derek Carr and the Oakland Raiders are close to finalizing an extension worth $25 million per season.

Carr had given the Raiders a deadline to agree upon an extension before the start of training camp.

The sides still are finalizing language, but the deal could be announced as early as the end of this week. 

Andrew Luck currently has the NFL's biggest contract at $24.6 million per season.

The Oakland Raiders hope to get former first-round pick Cordarrelle Patterson involved in their offense.

Patterson is hoping to revitalize his career after disappointing with the Minnesota Vikings. He had 132 receptions in four years with the team.

"He's a fun tool," offensive coordinator Todd Downing said. "I won't speak too much about how he was used in the past; that's somebody else's job. But I can tell you that we're going to have fun looking for ways to get him involved in the offense. He's a big, strong, physical, dynamic-with-the-ball-in-his-hands type player, and we're excited to see what he can do for us."

Patterson worked with six different quarterbacks while with Minnesota, none as talented as Derek Carr.

"You see what [Derek Carr] can do, and I've been watching him for a long time. He's one of the greats, and there's a lot of great quarterbacks out there," Patterson said. "Getting the chance to play with Derek Carr is an honor, to be here, and like you said, he's a great quarterback. So I'm just happy to be here."

Marshawn Lynch had the NFL's best-selling jersey during the month of May.

Lynch agreed to come out of retirement and sign with the Oakland Raiders in late April.

Derek Carr could become the NFL's first player to earn $25 million per season.

Carr and the Oakland Raiders are working on a contract extension.

Carr is giving the Raiders a deadline of the start of training camp to agree upon an extension.

Carr emerged last season as one of the NFL's best young quarterbacks.

Marshawn Lynch's deal with the Oakland Raiders contains incentives that could pay the running back an additional $5.5 million in 2017 and an additional $2 million in 2018.

Lynch has bonuses tied to rushing yards, rushing touchdowns, the Raiders making the playoffs, Lynch making the Pro Bowl, Lynch earning regular-season MVP honors and Lynch earning Super Bowl MVP honors, according to a source.

His two-year, $9 million deal with the Raiders contains $2.3 million guaranteed and has a max value of $16.5 million if he hits all his incentives.
