Daughter's tendon guard fell off her skate - simple repair options?

So, right after her team earned a spot at Nationals, my kid's tendon guard completely fell off her skate, and the other skate's guard is starting to go the same way. The guard itself isn't broken - the stitches that held it in place literally disintegrated and fell out. Both of my daughters have broken their guards in the past, but never after a single season of use, and never like this where the actual guard is still 100% intact but disconnected from the skate.

Has anyone ever seen this happen before? Is it fixable, or do we need to add the cost of a new set of skates to the already taxing price of traveling to Nationals in two weeks?
