Yes... you can get a concussion without being knocked out... but I don't think you can be knocked out without having a concussion. I could be wrong, but I think any blow to the head that causes you to be knocked out is most definitely causing a concussion... thus the reason why you were knocked out.

Now, if that fall is preceded by a traffic accident or a football player tackling you, then you might end up with one.
Helmets are tested by dropping them from adult head height with a weight in them. That's the baseline.
If it fails that, it won't protect you from anything worse and can't be certified.
Helmets protect against all sorts of injuries... Primarily they protect the skull itself from being fractured/broken. So undoubtedly a helmet is a GREAT thing to prevent injuries. However, you can't see if you caused a concussion by examining the exterior for injury. A sudden sharp movement of the head can result in the brain moving inside the skull and sustaining trauma (i.e. a concussion) while not causing any visible damage to the outside of your body.
That's why it is so difficult to diagnose concussions... there are often no signs outside... and a person might even be cognizant enough to pass simple "tests" and seem ok... but really have suffered brain damage from a concussion.
Anyone who thinks wearing a helmet is protection for a concussion has been severely mislead. I'm not saying that to insult you... but rather to caution you to be careful on that motorcycle! Seriously... be careful out there.

Exactly... and while I hate chasing things down the rabbit hole... I feel like concussion and head safety is a serious enough thing that it is worth a teaching moment even in a thread like this in case it helps someone be safer out there in the real world.
In the scheme of the show... the Walking Dead... I agree, it isn't a nit worth picking so I really didn't think much during the episode itself as to whether or not Morgan had gotten a concussion or hit his head or anything... I figured he was probably not sleeping much, not eating well, and so hyped up on adrenalin that the sudden shot to the gut, even a vest-protected gut, might have "shocked" his system enough for him to pass out.
