IRFU reveals latest plans to restructure All-Ireland League
Under the new agreement, the number of senior clubs is to be increased from 48 to 52, rolling substitutions are to be introduced on a trial basis and new regulations will come into place governing contracted provincial players.
The announcement follows a consultation process began in October 2009 and the latest structures will remain in place for five seasons in the hope of providing an air of badly-needed stability to the competition.
