Know it as fact mate. It's no surprise that he is still playing we have delayed a lot of surgeries over the years….Hell this year we have delayed surgery to Black, Delaney and Tarrant and thats just off the top of my head.
Blacks shoulder is so lose and painful that he is very hesitant to even tackle. You can't blame him for being hesitant as a subluxation is quite painful.
He was a good tackler last year too.
