When it says doubtful- 9 weeks, does that mean the injury lingers 9 weeks? Or does it range from being doubtful this 1 game to being out 9 games? How can I read this correctly?

It's just a projection to how long it should take them to fully heal. Every week it's a little random as to how much the player will recover. Some weeks are better than others and it could take less or more than that 9 week projection. If you want to play them when they're probably you're probably looking at 5-6 weeks in this case before they are listed as probable.

The penalty for an 11 ankle is no more than a 15 % off the ratting. That's makes him fast enough to play DT. In a pinch I would play him now, but would normally weight for that ankle to get to at least 50.
