The Raiders have wasted no time in trying to find another quarterback after starter Jason Campbell suffered a broken collarbone on Sunday.

Carson Palmer is high on the Raiders' wish list, Yahoo! Sports reports, but it is unlikely the Bengals would trade the veteran QB, who is semi-retired but still under contract with Cincinnati.

The Raiders have also inquired about David Garrard, who was released by the Jaguars before the season and turned down a non-guaranteed contract with the Dolphins, ESPN reports.

Kyle Boller replaced Campbell on Sunday and complete eight of 14 passes for 100 yards in the 24-17 victory over the Browns. According to ESPN, Campbell is expected to miss the remainder of the season.
