I'd switch to a proper upright wheel in the future when his foot is better and just not use flying saucers(there are many issues with them,especially with tiny robos that can get flung about far too easily not to mention the unnatural running position they create).I think the ideal wheel would be the Silent Runner in the 9 inch size(not Spinner,as I think that the Silent Spinner is a poor quality wheel overall and quite overpriced plus it isn't that safe and does have a feature known to cause problems among other pets due to the design allowing it to come apart in a dangerous manner even while in use).They're extremely durable,and no other wheel compares in safety features,plus they actually stay silent!

As far as the injury itself goes it should heal fine on its own with a proper cage set up.This means no wheel(especially not a flying saucer),keeping everything on a flat surface,and eliminating anything that could get climbed on.
