No, a fractured wrist is not drastic, in hindsight.

Irish's point was that many injuries cause a lot of pain, but are not life or disability threatening and will not get worse or more serious in a minute or two
("no blood, no bones, not a head injury" also neck/back).

That is the problem, knowing which category, and even if not "by the book"; if possibly any of the bold above, I would kill the play.
Yes, most of us do not have medical training, which is why we have to err on the side of caution, especially with minors.

In fairness & common sense, the runner should not be out (although out "by the book"); so killing it avoids that.
