Rubleva/Shefer withdrew because he has a groin injury.
The chances are that Langlois/Hay won't compete either, because her luggage still was not found (as of this morning), but there was no official announcement so far.
That, about Langlois/Hay, is just sad. There has to be some way to ensure that skates get there safely and on time. It's a shame, they were very nice at Skate America, and the programs would have been more polished by now.
