I don't mind there being a risk of injury in a walkover (even though I prefer it wasn't possible.)
The problem that I have is that the risk of injury in a walkover is bigger than the number of minutes played.
The calculation for probability of an injury seems to have been calculated over 48 minutes of the match, even though my players were only allocated 12 minutes each.
That means that they can be injured in the additional 36 minutes of a match and are not even credited for the minutes.
Hardly seems fair.
