Cardinals quarterbacks Carson Palmer and Drew Stanton are expected to be limited participants in Wednesday's practice, according to the team's official website.
Palmer is expected to do some throwing and could be healthy enough to return Week 6 against the Redskins. Stanton has not been medically cleared from a concussion, but can still do some throwing on Wednesday, according to the site.
If both quarterbacks can't play Sunday, the team will likely turn to Logan Thomas for the start against Washington.
