For football fans, the most devastating feeling one can have is to see your starting quarterback get injured early in the season and be out for the year.
Such was the case for New England Patriot fans when Tom Brady went down early in Week 1 of the 2008 season against the Kansas City Chiefs.

It can be a significant blow to the psyche of the fan. It can also hurt the momentum of a team.
The same can be said right around this time of the year for baseball fans. While injuries happen throughout the course of a season, August through October is the last possible time of the season you'd want to see the momentum of your team derailed.
With so many teams within a realistic grasp of the 2012 playoffs, truer words cannot be spoken.
The following teams certainly could not afford a major injury to their team as we head down the home stretch.
