Analysis: Dixon was signed with the Cardinals' quarterback situation uncertain. Carson Palmer is coming back from a nerve problem in his shoulder and backup Drew Stanton is recovering from a concussion. Neither may be available Sunday against Washington. That leaves rookie Logan Thomas as the only healthy quarterback on the 53-man roster.
