SPN's Adam Schefter reports that the Oakland Raiders have signed free agent quarterback Colt Brennan.

Terms were not disclosed.

A sixth-round pick (186th overall) in 2008 out of Hawaii by the Washington Redskins, Brennan did not appear in a game as a rookie, and spent the 2009 season on injured reserve. In two pre-seasons' worth of action, the 6-2, 212-pound quarterback completed 61.5% of his 96 pass attempts for 660 yards with 4 touchdowns and 3 interceptions.

Brennan re-joins former Redskins teammate Jason Campbell in a quarterback's meeting room that also includes Bruce Gradkowski, Kyle Boller, and Charlie Frye.
