Cardinals coach Bruce Arians said Palmer was able to toss the ball lightly at Tuesday's practice and will attempt to throw on the side Wednesday, Alex Marvez of FOX Sports reports. The Cardinals' bye week couldn't come at a better time for Palmer, who has been sidelined for the past two weeks after sustaining a shoulder injury in the season opener. Palmer will attempt to gradually attempt to increase his activity during his own workouts this week, before aiming for a return to practice in some capacity next Wednesday. His status for the Cardinals' Oct. 5 tilt with the Broncos still remains up in the air.
