When a team fields fewer than 3 players, a walkover occurs. The game will still be played, so the risk of player injury is still there, but the end score will appear as 25-0. (The team that fielded fewer than 3 players gets 0.) Also, training minutes will be distributed as 36 minutes for starters... I forget how many for backups and reserves. But players will all get the same minutes distribution regardless of how many minutes they actually played.
