What is going on with the injuries?

By my count, there are TWENTY-TWO players on the 1-Game and 6-Game injured lists combined. Some of these players (Butler, Olson, Washington) have been in the IL all season. One of those players is recovering from an off-season injury. What has been confusing is that many of these injuries happen during practice.

Has there been any research as to why the Tiger-Cats have been "bit by the injury bug" so severely over the past 3 seasons? From another thread:

I also remember Kent Austin mentioning that they haven't even practiced with pads all season. This is why the number and severity of injuries is perplexing...
