Could be, or it could be he just passed out standing up. When he was alive, my dad had severe atrial fibrillation and would frequently near pass out and would stumble or catch himself and he fell a few times. It's a blood flow to the brain issue. Something similar to orthostatic hypotension.

One time as a family we got up from lunch and walking to the car he micro passed out and I had to help catch him. So this could happen. I'm keeping Senator Fetterman in my prayers either way, though the picture he posted does not look like he needed 20 dang stitches. It looks like a little cut between his eyes and a lot of smeared blood.
