This is why "decision day" around the NFL will go down to the wire. Entering Week 9, 13 teams have recorded at least five wins this season -- the third-most through Week 8 since 1970.

Cincinnati Bengals running back Samaje Perine was injured during the second quarter of the team's NFL Week 9 game against the Chicago Bears.
