After the high dribbling, he sat on the bench down by the scorers table for a couple of minutes. He then got up and went back to the locker room with a painful look on his face while holding his hand/arm against his stomach.
I saw this too. He sat down on the bench with a brace on and was raising it above his head and kind of doing some testing movements, it seemed like, to see if it would pop out again before he went back in the game. I looked back as he was standing up and holding it in pain against his stomach, and it looked like it had popped out again. Once a shoulder pops out, it often happens more easily, especially right after. Obviously there's no way of us knowing if there was actual structural damage from this one, but I'd hope there wasn't if he was testing it after the first one, and based on the fact he's not wearing a sling later in the week. I think this is something that you can play through, but there is a risk of it popping out again, which could cause structural damage, I'd assume. I wouldn't completely give up hope for next week, but also wouldn't be surprising if we don't see him suit up.
Disclaimer, I'm not a doctor, but have been around people with lots of shoulder issues, lol
