That content provided by the club from Quaynor with the GoPro didn’t look good for Kreuger. He wasn’t wearing a sling and it wasn’t iced, but he was holding his jumper with his hand in such a way that he didn’t move his left arm at all.
That's all I saw which is why I assumed slight A/C tear, until you told me that it wasn't.
I still haven't even seen the actual replay of the injury occurring. Where is it? I'm lazy.
