More cancellations announced today with Ulster's match on Friday against the Ospreys called off. Connacht's clash with the Dragons has also been cancelled. There's also talk of Munster's game being moved to Thomond Park. Both Musgrave and Thomond's pitch are under cover and there'll be inspections on Friday and Saturday. Given how cold it is in Dublin, I'd be surprised to see the Leinster Glasgow game going ahead at the RDS, even if the pitch is playable I doubt conditions will be safe in the surrounding area.
