Extra Spice in the Eagles v North Clash

There is extra interest and spice in the Eagles v North game generated by the fact that a few players will be playing against their old clubs. ie - Grocke, Oakley (now Eagles and last year at North) and OHara (now North and last year at Eagles). The OHara v Dabrowski/Lindsay (if Lindsay gets a game) clash looms as especially significant. Did OHara play in the trial last week - he wasn’t named? Is their an injury cloud hanging over him?
What about other games? Any more examples of players playing their FIRST game against their old club?
