Bills head coach Doug Marrone declared his two key starters game-time decisions after practice on Friday. Johnson did not practice all week, and is only returning to team headquarters today after spending the week away to mourn a death in the family. Gilmore returned to the practice field this week after preseason wrist surgery, and the thought is that if he plays, he'll have some sort of protective implement on his wrist - perhaps even a club.
C.J. Spiller is also listed as questionable for the Bills, but Marrone has stated this week that his star running back is ahead of where he was last week, when he suited up (albeit for a limited role) in Cleveland. Marquise Goodwin and Jairus Byrd will be available to play, as has been reported all week, but nickel corner Ron Brooks isn't quite ready to return from post-Week 1 foot surgery. EJ Manuel, of course, has been ruled out, with Thaddeus Lewis assuming his starting role.
Here's the full injury report for both the Bills and the Bengals heading into Sunday's game.
