Herbert was on the field with teammates Monday but largely took in the workout as a bystander. He's recovering from surgery to repair the torn labrum in his left, non-throwing shoulder.
Head coach Brandon Staley said Herbert's status for offseason team activities will be "up in the air" while the team monitors his progress.
"We're going to listen to the doctors, and I know he's making progress," Staley said, "Again, we'll have those updates as we get closer to practice time."
Herbert, 25, was not listed on the injury report before the wild-card playoff loss to the Jacksonville Jaguars.
