Call Me PJ no where to be seen again.

Just wondering does anybody know why he was a non runner for the last 2 nights on the trot?. What interests me is that he was withdrawn pretty late in the day on both occasions. Not suggesting anything sinister is going on but he has seemingly been heavily backed on both occasions causing hefty rule 4s on both occasions. I wonder did the horse leave for Tipperary at all last night or indeed for Down Royal this evening. Can anybody shed any light on this situation . Thanks in advance.
