Bears beat writer Kevin Fishbain offered these observations from the first hour of Wednesday's Bears practice via Twitter:
• Jonathan Scott has ice on his right knee ... Bears confirm signing of DE Josh Williams, terminate contract of Turk McBride.
• Not sure where Tim Jennings is, Zack Bowman opened as CB opposite Tillman ... Cory Brandon 1st team LT ... James Brown at guard.
• Attempt 2 at Vine with TE catch drills.
• Bears OLT Jermon Bushrod in shorts and still wearing a walking boot ... injured his calf on Monday. Marshall back and practicing.
• The Bears' new look at linebacker: Briggs, two new vets, two draft picks. My story on the dynamic in the LB room
