We are roughly one-fourth of the way through the NFL season -- and it hasn't disappointed thus far. Entering Week 5, this is where the contenders begin to separate themselves from the pretenders. As teams prepare for their opponents this week, they also have to assess the injuries among their players.
It was a tough week for some squads that suffered critical injuries to some top players. The Chicago Bears lost their starting running back, David Montgomery, after he sprained a knee against the Detroit Lions. According to ESPN's Dan Graziano, he could miss four to five weeks, a tough blow given how he he played last week.
