So I’m just gonna preface this tweet with I am a physical therapist. I watched the video like 50 times now. it’s hard to tell what exactly happened since there are people in front when the event happened as well as he’s wearing long pants, but from what I could observe+
just by his gait (and personal experience walking on cobblestone which is what it looks like in the video), it’s really easy to misstep, but his gait gradually started to improve. It looks like he possibly rolled his ankle. He was still walking on it, but because of the acute+
nature of it, it probably just hurt a lot and is shocking at first (Why he used manager for support). The fact he could still bear weight on it is a good sign. If it was a worse injury, he would likely not put weight on his left foot, or would have needed another member to help.+
He should definitely stay off it for the next couple days, rest, ice, and elevate is the best thing for him now. Most certainly it hurt, as any sprained ankle does, but as long as he takes those precautions, then he’ll be just fine.+
Okay, Ness? Don’t worry too much, for now. Hoping of course it’s nothing more than a twisted ankle. 
I hope I could help ease some of your worries as best as I know how.
