The truth ,the whole truth and nothing but the truth so help me God,,,,or the Fai
Within a club,if they have more than one junior team an they enter only one team in the Fai or Mjc then all the registered junior players are available for selection.
However if the club enters one or more teams then the players are only entitled to play with one team in the competition,and if they for example get knocked out in the 1st round with the B team they cant play with the A team in the next round .
A basic rule within the Fai/MFA and Aul etc etc is that a player is only entitled to play with one team in any competition.
With regards to Pearse A v B , thats the luck of the draw Killer;)
