Once a player is injured, a Doctor will also help him heal more quickly,
 No I don't..
^^ read that . which is the full damn statement  i made and the rule guide post which is fact.. which is the point  I was relating too not overall to holy  role, but  the point of  concern.  Doctor help them  get better  after the injury more quickly..  read the full statement.
  Your reading is flawed. A doctor help reduce  the severity of a player injury.. then it lead to how he does it. which I posted.  the first  part is  leading statement not the whole statement.. just a opening statement.
 A doctor cant  truly prevent a injury. All he can  do is  put them in the good after the injury.
