We may have been waiting to see how the situation at the Bulls pans out - it has only been in the last couple of weeks that their board was given formal clearance by the RFL after all.
At the presentation night GM said that the Dr arrangements with Bradford would continue but that the specific details had yet to be discussed. Seeing as Bradford have gone through some personnel changes recently I'm sure that is still the case.
It is interesting to note that in the RFL document about the game's future they anticipated a DR system being in place but probably limited to about three players. They also anticipated such a system operating between tier 2 clubs and tiers 4 and 5, which might be interesting.
