Why isn't UConn's real "Jonathan The Husky" mascot in Houston for the Final Four?

While Butler's real bulldog mascot, Blue II, has become the media darling of America, garnering a lot of free face and airtime for Butler University from his spa visit on wednesday to his chartered plane trip on Friday to staying at the 4-star Intercontinental (first ever canine guest) with all sorts of special perks at the Johnson Space Center, etc., we have heard nothing at all about Jonathan of UConn. Did he die or what?
