Quarterback Carson Palmer helped the Raiders last year by restructuring his contract. He isn't intent upon doing so again this year, according to a report Monday.
An ESPN report said Palmer is "highly unlikely" to redo a contract that calls for Palmer to earn $13 million in base salary this season.
Last season, Palmer helped the Raiders save more than $9 million in salary-cap room by restructuring his contract.
Palmer's base salary dropped from $12.5 million to $825,000, in exchange for an $11.675 million signing bonus spread out over five years. In terms of dollars, Palmer ultimately will receive the same amount he originally was scheduled to make. Palmer counts $15.335 million against the cap for 2013, with $2.335 million coming as a result of the prorated portion of the signing bonus.
The Raiders have restructured a few contracts this offseason to free up cap room. Restructuring Palmer's contract a third time -- the first time came after the Raiders traded for him in 2011 -- would give the Raiders even more space.
If Palmer balks, the Raiders could cut him or pay him under his current contract. Palmer would count $9.34 million against the cap if he is cut, though the Raiders would get out from under the $13 million base salary this season and $15 million base salary for 2014.
Palmer was unavailable for comment. A Raiders spokesman said the team's policy is not to comment on contract situations.
Jenkins played for Dallas his first five NFL seasons. Porter spent last season with Denver after playing his first four seasons with New Orleans.
The Raiders do not have a proven starting cornerback. Ron Bartell and Shawntae Spencer started in the opener last season, but Bartell was released late in the season and Spencer's one-year contract expired.
Earlier this month, the Raiders talked to veteran cornerback Terence Newman. As of Monday night, Newman said he still hasn't decided whether to re-sign with Cincinnati or come to Oakland.
This year's draft features several highly regarded cornerbacks. Some mock drafts project the Raiders taking Alabama cornerback Dee Milliner with the third pick of the first round.
