Just one carry up the gut
You'd be fine then, unless you're 130 pounds.
Look, I'm not trying to be a badass and be like "yeah I'd probably stiff arm everyone on the way to the endzone!" or anything like that. It would hurt, and you'd likely be sore the next day.
But ONE carry? Concussions, hospitalization? Geez people wtf. If you're a grown frickin man, wearing full pads mind you, taking ONE hit wouldn't hospitalize you unless it was dirty and to the head, assuming you aren't a fatass lazy couch potato. If you're moderately active and in shape, I don't see why one hit would do any real damage other than being sore.
And yes, I realize these are professional football players. They're huge, they're big, they're fast, and they tackle people for a living. I'm not saying it wouldn't hurt. It'd likely knock the wind out and you'd definitely feel it the next day. But c'mon man...it's ONE single tackle. You'd be fine.
