Quarterback Carson Palmer has been traded from the Oakland Raiders to the Arizona Cardinals for a conditional seventh-round pick in the 2014 draft, a league source told ESPN NFL Insider Adam Schefter. The Raiders will receive the draft pick if Palmer starts 13 games for the Cardinals in the 2013 season. Palmer dined with Cardinals team personnel Monday night, sources told ESPN. Palmer will help solidify a Cardinals quarterback position that has been in flux since Kurt Warner retired after the 2009 season. Quarterback Drew Stanton signed with Arizona last month, following new coach Bruce Arians to the Cardinals from the Indianapolis Colts. At the time of the signing, Arians said he was confident Stanton could handle the starting job, but it's expected Palmer would move into the top spot once a trade is finalized. On Monday, the Cardinals released quarterback John Skelton, who started 17 games for the team in the past three seasons. The Raiders decided to move on from Palmer, acquiring quarterback Matt Flynn in a trade with the Seattle Seahawks on Monday. Palmer put up prolific numbers in his first full year as a starter in Oakland, but that led to little success for the team. He completed 61.1 percent of his passes and threw for 4,018 yards in 15 games -- second most ever for the Raiders -- with 22 touchdowns and 14 interceptions. The 33-year-old Palmer, who is owed $13 million this season, was unwilling to take a pay cut to remain with the Raiders, according to sources. "I talked to Carson I guess it was probably Saturday, over the weekend, and kind of explained where we were at, what the process was. I think he and his representation totally understand where we're at," Raiders coach Dennis Allen said Monday in a conference call to discuss the acquisition of Flynn.
