Not Terrible
This is exactly it, I expect most quicks are willing to bruise an opponent but a serious injury? A life threatening injury?Also, actual bad injuries are quite rare. You don't tend to see bowlers looking too concerned if they whack a guy on the arm below the shoulder, or the stomach or whatever. It's only usually when the head is involved or the batsman shows signs that he's seriously hurt that bowlers will check to make sure he's OK.
Completely different story. No one wants that.
