I don't get why?
I said it earlier in the thread, the stability and strength test the trainers would have done on Ragland when the injury happened would have told them it was Grade III sprain. It's more accurate than an MRI. Unless the Bills are being hush hush, which if it was completely torn there would be no point, I'm not so sure I would just assume he's out for the season.
The problem becomes when it's not completely torn or a Grade II sprain. They can't tell what the status is, as in, how much it's partially torn until they can get an accurate MRI. It could be it's not torn at all, and is just been stretched.
IMO, I think at this point, worse case is it's a Grade II sprain, which might put him out 4-6 weeks.
