There is still plenty of time remaining until the final roster has to be set for the Bears, yet for the players who are on the bubble, it's time to put up or shut up.

The second game of the preseason is Monday night against the Giants and, as always, the final score matters little in comparison with the evaluation for the final spots on the 53-man roster.

While the skill positions at QB, running back and wide receiver are fairly well set in stone, there is the question of whether the team will keep five or six wideouts, and if they will maintain three or four backs.

On defense, the starters are also known, although safety, defensive tackle and cornerback (other than Charles Tillman, of course) do have some room for further consideration.

Meanwhile, that offensive line does not seem to be final, despite what Mike Tice has said. In fact, he left himself room for changes by stating that the starting five are set "unless they falter." And falter they certainly did against Buffalo.

So let's see which players face the guillotine if they don't step up and play well in the remaining preseason games.
