Certainly a possibility.  Unfortunately, this specimen has not been
adequately described (a new study of this animal, not by me, is underway).
Some elements as photographed are non-"_Tarbosaurus_"-like (two, the
presence of a retroarticular process and procoelous cervicals, are
non-tyrannosaurid-like).  A problematic taxon at present.
