Leinster have said they've released him already (to the ARU to train, not from his Leinster contract). It's a pretty strange situation, someone needs to clarify it from either Douglas' side or the ARU's.
It would appear that the Reds (and the ARU) may be in negotiations with Leinster, if that is the case, nothing will be said that may affect those negotiations.
It would be wonderful to see him back (even in Red), I rate him highly as a bloody good lock with a big motor who does the hard tight stuff.
