Sam Warburton will not be picked by the Cardiff Blues until the dispute in Welsh rugby has been resolved.
The Wales captain signed a central contract with the WRU last season, and as part of an agreement with Regional Rugby Wales, the regions will not field any players contracted to the union until the current dispute between the two has been resolved.
With no Participation Agreement currently in place between RRW and the governing body, Warburton will have to wait until a deal is struck before he can play for the Blues, with whom he has been training over the summer.
And with the region preparing to start their pre-season this Friday against Exeter, Warburton will find himself waiting on the sidelines.
"Until things have been sorted out, unfortunately we can't pick Sam," backs coach Paul John told Wales Online.
"He has trained really well. It's probably one of the first pre-seasons he's had in a long time and he's been a big part of training this summer.
"So hopefully, fingers crossed, things will get sorted and he can start playing.
"He's been excellent in training. He was rehabbing from his dislocated shoulder to start with.
"I know Dale [McIntosh] has spoken to Warren Gatland about it and there is a plan in place about how many games he can play and things like that.
"From a rugby point of view, we just hope to start integrating that plan as soon as we can.
"I just know at the moment he is unavailable to play until everything gets sorted, signed and sealed, and we can crack on then."
