Johnson (lower leg) didn't practice Monday, Ryan Miller of the Rochester Democrat and Chronicle reports.
Per the report, Johnson, who hasn't practiced since Aug. 8, was on the field before Saturday's preseason game against the Browns wearing a sleeve on his right leg. At this stage, he doesn't seem likely to suit up for the Bills' exhibition finale, but when he is able able to return to the field, Johnson will have a chance to re-enter the equation in a Buffalo backfield led by James Cook that also includes Ray Davis.
