Fewer teams than expected will participate in next season's Premiership after Llanelli's withdrawal from the competition.
The Welsh Rugby Union's original plan was to increase the amount of teams from 12 to 14, but after Llanelli's decision to go into hibernation for a season they have settled on 13.
WalesOnline has seen a letter sent to all Premiership and Championship clubs from WRU Community Director Geraint John.
