The Raiders have traded wide receiver Louis Murphy to the Panthers. Oakland has Denarius Moore, Jacoby Ford, Darrius Heyward-Bey and great depth at the position. The terms of the deal have not been released.

The Raiders created $3.8 million in cap space when they signed Tyvon Branch to a long-term contract earlier this month. The safety received a four-year deal after Oakland had tagged him. Branch's new deal dropped his cap number from $6.212 million down to $2.4 million -- creating roughly $3.8 million in total cap space for the Raiders in 2012. The four-year, $26.6 million contract has an annual average of $6.65 million.

Despite three consecutive 1,000-yard rushing seasons, Cedric Benson remains without a contract for 2012. Benson has fielded "check-ins" from the Packers and Jets, along with the Raiders. He turns 30 this season, but said he has no interest in taking the veteran minimum.

The Raiders and Tyvon Branch have agreed to terms on a four-year deal, according to multiple media reports. The deal is worth $26.6 million and includes $17.1 million in guarantees for the safety. Oakland originally placed their franchise tag on Branch on March 1 and the former fourth-round pick signed the tender in May.

The Raiders will give the Oakland school system a check for more than $50,000 as part of a season-ticket drive designed to benefit schools. The team donated 10 percent of the gross proceeds of new season tickets purchased and paid for from May 1 to June 30 to the Oakland Unified School District.

Long-time Raiders defensive end Ben Davidson died Monday night. He was 72. Davidson gained fame as a member of the Raiders. He played for the the Raiders from 1964-71, appearing in 110 games for the team. Raiders owner Mark Davis said by phone that Davidson passed away after a lengthy illness. "He was larger than life to me," Davis said. "The handlebar mustache, the motorcycle-riding. He was a rebel. ... (He was) one of so many unique individuals on the Raiders."

With some time to reflect and the first true break in the NFL calendar since the passing of Al Davis, longtime friends and associates will get together in Las Vegas this week to memorialize him. Davis passed suddenly on Oct. 8, 2011. Oakland responded with an inspired win the following day in Houston -- arguably their best game of the year -- and then held a public memorial in a sold out game against the Browns.
