The Oakland Raiders have agreed to sign Trent Richardson.

Richardson was released this offseason by the Indianapolis Colts.

The Raiders lost Darren McFadden to the Dallas Cowboys and Maurice Jones-Drew to retirement at running back.

The Oakland Raiders have signed Christian Ponder.

Ponder will be the Raiders' backup at quarterback behind Derek Carr.

Ponder was a first round pick out of Florida State by the Minnesota Vikings.

Darren McFadden has agreed upon a two-year deal with the Oakland Raiders.

Jerry Jones was a big admirer of McFadden in 2008 in the draft, but was unwilling to sacrifice the cost to move up to draft him out of Arkansas.

McFadden will help the Cowboys replace DeMarco Murray.

Malcolm Smith has agreed to sign with the Oakland Raiders.

Smith was Super Bowl MVP in the Seattle Seahawks' win over the Denver Broncos.

The Cleveland Browns, Oakland Raiders and Kansas City Chiefs will pursue Darrelle Revis in addition to the New England Patriots and New York Jets.

The Patriots decided not to pick up Revis' $20 million option for 2015.

The Browns and Raiders also pursued Revis in 2014.

Julius Thomas has agreed to sign with the Jacksonville Jaguars.

The Seattle Seahawks, Oakland Raiders and Denver Broncos also pursued Thomas

Thomas has been one of the NFL's most productive tight ends over the past two seasons after coming back from ankle surgery in which he missed all of 2012.

Thomas was a fourth round pick by the Broncos in 2011 out of Portland State.

AEG has decided to abandon their plans to build a football stadium in downtown Los Angeles.

AEG invested at least $50 million and five years in their efforts to build a stadium.

“I think it’s fair to say we have turned our attention to proceeding with an alternative development,” AEG Vice Chairman Ted Fikre said.

The St. Louis Rams are seeking a stadium in Inglewood, while the Oakland Raiders and San Diego Chargers are working on a proposal in Carson.

Eric Grubman, NFL executive vice president and point man for the league on L.A., said the league has been "very interested" in the downtown site and has spent significant time with senior members of AEG. “We would always prefer to have an excellent site in the mix, but we recognize that it is not in our control.”

Maurice Jones-Drew has retired from the NFL after nine seasons.

Jones-Drew spent eight seasons with the Jacksonville Jaguars before joining his hometown Oakland Raiders in 2014.

Jones-Drew, 5-foot-7, 210 pounds, completed his career with 8,167 rushing yards. 

The Oakland Raiders will have Ndamukong Suh in for a visit next week.

Suh is the biggest free agent of the offseason class and also will draw serious interest from the Miami Dolphins and Indianapolis Colts.
