You need to recognize that the injury report rules have changed.
You do not list them in a category (questionable, probable, doubtful).
You only report their participation in practice.
Some players did not practice today so they are listed.
Today was a light, walkthrough, so missing it wouldn't be a big deal.
Every player in the NFL in January has an injury of some sort.
With Hobbs for example, it is common that any DB receive treatment on his legs. Probably just about every player spends time in the training room at this point in the season, so the guys who are not at practice go on the injury report, and whatever they were being treated for is listed.
This is nothing.
