At the bottom notes of an article mostly about Dana White talking about boxing there is this note about MacDonald fighting in UFC 72 in Ireland (hopefully not too soon after the beating he got from Franklin):
"NOTES: It appears Canadian Jason MacDonald's next UFC opponent will be Rory Singer, an alumnus of The Ultimate Fighter reality TV show. The middleweight from Red Deer, Alta., has confirmed he will fight at UFC 72: Victory on June 16 in Belfast. Singer says in an Internet posting that he will be the Canadian's opponent. . . ."
