It's a positive sign that Jay Cutler practiced today, even if it was on a limited basis.
Cutler missed the second half of Sunday's game against the New York Giants with a concussion. His mere participation in the practice means he passed an important step, giving doctors enough confidence to let him even exert himself. Now, after his limited work, Cutler will be evaluated again to see how he handled the physical exertion.
At some point, though, as Bears coach Lovie Smith pointed out, an independent doctor will have to give him the green light in order to play.
"Before he goes back out onto the football field," Smith said, "he'll have to be checked out by an independent doctor, independent physician before he's completely released to play in the football game."
So, there is reason for optimism, but he's not out of the woods quite yet.
