Actually, if there is a late withdrawal the federation can choose any skater they want on the SB list as a replacement. Usually, federations will choose the cheapest and easiest replacement since they pay the travel cost. However, there is also the possibility that there will be no replacement as seems to be the case with Daniil Samsonov's withdrawal from Skate America.I wonder who will replace Rika? Maybe Yuhana? She is already going to America and Canada is not too far. Praying Mai Mahara gets her spot as she only has one event so far.
