The Texans will have plenty to mull over as the clock ticks towards the start of the NFL season. Considering the timetable for Arian Foster’s return could range from September to November, they are not likely to rush to make a decision, nor should they. Better to observe how he progresses and evaluate further when there is more information.
Assuming his progress is solid, it seems reasonable Foster could avoid the IR designation altogether. But when he is able to take the field for the first time may not matter as much as staying on it week in and week out. Foster has his work cut out for him over the next few months to prove not only that he can come back to full health, but that he can maintain it.
This is a pretty in-depth article about Foster's injury. But obviously the decision is whether to put him on IR designated to return or not. They want to avoid a healthy Foster sitting on the sideline not being able to play because he progressed well. On the flip side, returning too soon could also be a potential disaster. Taking Foster in drafts will be risky, but obviously the later you can snag him the better.
