Shazier will still need a battery of tests on the spinal canal bones, discs and ligaments, as well as measurement of the room the spinal cord has. There are several hurdles before he can play, but for now let's rejoice at the news of what seems to be the best-case scenario.
It is way too early to tell (or care) about Shazier’s career.
We can at least be optimistic at this point that he will walk again.
If it is a spinal cord concussion, he is truly fortunate.
When a player isn't moving his legs or having feeling in the lower extremities, it is not often that spinal cord concussion is the reason. The chances of this are like that of completing a hail Mary pass – not zero, but not expected.
