Sterling Shepard was on the field Monday for stretching and some early individual drills, an indication he is not overly symptomatic as he remains in the concussion protocol for the second time this season.
The activity is a promising development, although there are many obstacles left before Shepard has any chance whatsoever to play Sunday against the Cardinals. He suffered a concussion in the season-opening loss to the Cowboys and sustained a second concussion four weeks later in the loss to the Vikings.
The proximity between the first and second concussion is alarming and a reason for extreme caution, which is why Shepard is not expected to clear the protocol this week.
