Barkley completed just eight of his 24 attempts for 121 yards and an interception in Friday's preseason loss to the Raiders.
Barkley was extremely inefficient Friday, and he threw a crucial interception in the red zone on the Cardinals' opening drive of the second half. Barkley is seemingly behind the more experienced Drew Stanton on the depth chart at the moment, and the results of his first fore into preseason action were not all that encouraging of his chances of overtaking the latter in the pecking order.
